Have you ever read a sentence containing the word “bestial” and wondered what the writer really meant?
Perhaps you’ve seen a phrase such as:
The prisoners were subjected to bestial treatment.
Or:
A bestial roar came from the forest.
At first, these examples may seem confusing because “bestial” is closely connected to the word “beast.” And that connection is actually the easiest way to understand it.
The word bestial can describe something that is like a beast or animal, but when it describes human behavior, it usually carries a much stronger meaning: cruel, savage, brutal, or lacking normal human compassion. Oxford and Cambridge both describe bestial as a formal adjective with these meanings.
In this guide, I’ll explain the bestial meaning, show you how to use it naturally, compare it with similar words, and give you practical examples that make the meaning easier to remember.
What Does “Bestial” Mean?
Bestial is an adjective.
It has two closely related meanings:
- Like a beast or animal
- Extremely cruel, brutal, or inhuman
For example:
The creature had a bestial appearance.
Here, bestial means beast-like or animal-like.
Now consider:
The prisoners suffered bestial treatment.
Here, it means the treatment was extremely cruel or inhuman.
So, a simple way to remember the word is:
Bestial = like a beast, especially in a savage or cruel way.
The exact meaning depends on the context.
Bestial Meaning in Simple English
If I had to explain bestial in the simplest possible way, I would say:
Bestial describes something that seems savage, beast-like, or extremely cruel.
For example:
The soldiers were accused of bestial acts.
This means the soldiers were accused of acts that were extremely cruel or brutal.
But:
We heard a bestial roar.
Here, the word describes a sound that was wild, fierce, and animal-like.
That’s why context matters so much when you’re learning this word.
Bestial as an Adjective
Because bestial is an adjective, it describes a person, thing, action, behavior, sound, appearance, or condition.
For example:
It was a bestial attack.
He displayed bestial cruelty.
The prisoners endured bestial treatment.
A bestial roar echoed through the forest.
The story features a bestial creature.
You can also use it after a linking verb:
His behavior was bestial.
The creature looked bestial.
The treatment was bestial.
This is a normal adjective pattern in English.
1. “Bestial” Meaning Cruel or Inhuman
This is probably the most important figurative meaning to understand.
When bestial describes human behavior, it usually suggests that the behavior is savage, brutal, cruel, or without normal human compassion.
For example:
The prisoners were subjected to bestial treatment.
This means they were treated in an extremely cruel and degrading way.
More examples include:
The report described several bestial acts of violence.
The victims suffered bestial cruelty.
His bestial behavior shocked everyone in the room.
The attack was described as a bestial act.
In these sentences, bestial is much stronger than simply saying bad or unpleasant.
It suggests behavior that is so savage or cruel that it seems almost inhuman.
Cambridge describes the word as formal and disapproving, while its American definition emphasizes behavior that is fierce, cruel, and without human feelings.
2. “Bestial” Meaning Like an Animal
The second major meaning is more literal.
Something can be described as bestial when it resembles a beast or animal in appearance, behavior, or sound.
For example:
A bestial creature emerged from the cave.
Here, bestial means the creature looked or behaved like a beast.
Another example:
A bestial roar came from the forest.
This means the roar sounded wild, fierce, or animal-like.
You might also see:
The character had a bestial appearance.
This suggests that the character looked unusually wild or beast-like.
This meaning is especially useful in fiction, fantasy, horror, mythology, and descriptive writing.
Bestial in a Sentence: Practical Examples
Let’s look at some examples in different contexts.
Example 1: Human behavior

Meaning: The dictator was responsible for extremely cruel or savage actions.
Example 2: Treatment

Meaning: They were kept in extremely harsh, degrading, or inhumane conditions.
Example 3: Animal-like sound
A bestial roar suddenly echoed through the valley.
Meaning: The sound was fierce and animal-like.
Example 4: Fiction

Meaning: The creature had the qualities or appearance of a beast.
Example 5: Human nature
The novel explores the bestial side of human nature.
Meaning: The novel examines primitive, savage, or violent human instincts.
Notice that the meaning changes slightly depending on what bestial describes.
Common Collocations With “Bestial”

Bestial vs. Beastly
One of the easiest words to confuse with bestial is beastly.
They come from the same general idea, but they are not always interchangeable.
Bestial
Usually means:
- savage
- cruel
- brutal
- inhuman
- beast-like
For example:
The prisoners suffered bestial treatment.
Beastly
Beastly can also mean unpleasant or unkind. It is especially associated with British English and can sound old-fashioned in some uses. Cambridge gives examples such as “beastly weather” and describes the word as mainly UK and old-fashioned.
For example:
We’ve had beastly weather all week.
Here, beastly simply means very unpleasant.
So I wouldn’t normally use bestial to describe ordinary bad weather.
A useful rule is:
Bestial → savage, brutal, or beast-like
Beastly → unpleasant, unkind, or horrible
There is some overlap, but their everyday usage is different.
Bestial vs. Brutal
Brutal is probably the closest everyday synonym for the figurative meaning of bestial.
Compare:
It was a brutal attack.
and:
It was a bestial attack.
Both sentences suggest extreme violence.
However, brutal is much more common in everyday English.
Bestial sounds more formal, literary, and strongly disapproving.
For example:
The newspaper described the attack as brutal.
sounds relatively ordinary.
The newspaper described the attack as bestial.
sounds more forceful and literary.
So, if you’re having a normal conversation, brutal may be more natural. If you’re writing formal or descriptive English, bestial can provide a stronger stylistic effect.
Bestial vs. Animalistic
These two words are also related, but there is an important difference.
Animalistic generally means resembling animals or animal behavior.
For example:
The character displayed animalistic instincts.
This doesn’t necessarily mean the character was cruel.
But:
The character displayed bestial behavior.
usually carries a much more negative meaning and can suggest savagery, brutality, or a loss of civilized behavior.
So:
Animalistic → animal-like
Bestial → beast-like, often with a strong sense of savagery or cruelty
This distinction is particularly useful when you’re choosing vocabulary for essays or creative writing.
Bestial vs. Brutish
Brutish is another related adjective.
Both bestial and brutish can describe behavior that lacks civilized qualities, but they don’t always emphasize exactly the same thing.
Bestial
Usually focuses on savagery or cruelty.
The soldiers committed bestial acts.
Brutish
Can suggest someone is rough, uncivilized, insensitive, or lacking refinement.
His brutish manner made conversation difficult.
There is some overlap between the words, so context is important.
How to Use “Bestial” Grammatically
Because bestial is an adjective, there are two especially useful sentence patterns.
Pattern 1: Bestial + noun
bestial behavior
bestial cruelty
bestial treatment
bestial attack
bestial creature
For example:
The article described the bestial treatment of prisoners.
Pattern 2: Subject + linking verb + bestial
His actions were bestial.
The creature looked bestial.
The treatment was bestial.
These patterns are simple and grammatically natural.
Can “Bestial” Describe a Person?
Yes, but you should use it carefully.
For example:
The novel portrays the villain as a bestial figure.
This suggests that the character is savage, brutal, or beast-like.
You can also say:
His behavior was bestial.
This is often more precise because you’re criticizing the behavior, rather than simply labeling the entire person.
Calling a real person bestial is a very strong negative judgment. Because the word is formal and disapproving, it should be used when the context genuinely justifies that intensity.
Is “Bestial” a Formal Word?
Yes.
Both Oxford and Cambridge identify bestial as a formal word, particularly in its sense of cruel or inhuman.
You’ll most likely encounter it in:
- Formal articles
- Newspapers
- Essays
- Historical writing
- Literature
- Political commentary
- Fiction
- Academic or descriptive writing
In casual conversation, people are more likely to say:
That was extremely cruel.
rather than:
That was a bestial act.
The second sentence isn’t wrong. It simply has a stronger and more formal tone.
How to Pronounce “Bestial”
Oxford lists bestial as:
/ˈbestiəl/
The pronunciation can vary somewhat between accents, but a learner-friendly approximation is:
BES-tee-uhl
Cambridge also gives /ˈbes.ti.əl/ for both its UK and US entries.
When learning the pronunciation, focus on saying the word smoothly rather than separating every syllable too strongly.
Bestial Word Family
Understanding related words can make vocabulary learning easier.
Beast
A large or wild animal, or sometimes a person who behaves cruelly.
Bestial
An adjective meaning beast-like, savage, or cruel.
Beastly
An adjective meaning unpleasant or unkind, and in some contexts beast-like.
Bestiality
A noun with more than one dictionary sense. In formal usage it can refer to extremely cruel behavior; it also has a separate specialist sexual meaning involving humans and animals.
Because bestiality has that separate specialist meaning, don’t assume it simply means “the quality of being bestial” in every context.
For most English learners, the important word here is simply bestial.
Synonyms for “Bestial”
The best synonym depends on the context.
When bestial means cruel:
- Brutal
- Savage
- Cruel
- Barbaric
- Inhuman
- Merciless
- Brutish
For example:
The attack was bestial.
could become:
The attack was brutal.
When bestial means animal-like:
- Beast-like
- Animalistic
- Feral
- Wild
- Savage
For example:
The creature had a bestial appearance.
could become:
The creature had a beast-like appearance.
Remember that synonyms are rarely perfect replacements. Bestial has its own formal and strongly negative tone.
Antonyms of “Bestial”
If you’re looking for words with the opposite meaning, consider:
- Humane
- Compassionate
- Kind
- Gentle
- Merciful
- Civilized
For example:
The prisoners were subjected to bestial treatment.
The opposite would be:
The prisoners were treated humanely.
Or:
The organization provided compassionate treatment.
This contrast makes the meaning of bestial easier to understand.
Common Mistakes When Using “Bestial”
Mistake 1: Thinking “Bestial” Simply Means “Animal”
Not every animal-related thing is bestial.
Incorrect or unnatural:
I bought a bestial book about dogs.
If you simply mean a book about animals, say:
I bought an animal book.
or:
I bought a book about dogs.
Bestial suggests something more specific: beast-like, savage, or cruel.
Mistake 2: Using It as a Noun
Because bestial is an adjective, you cannot normally use it as a noun.
Incorrect:
The bestial attacked the village.
Better:
The bestial creature attacked the village.
or:
The creature behaved in a bestial manner.
Mistake 3: Using It for Mildly Bad Things
Because bestial is a strong word, don’t use it simply to mean “bad” or “terrible.”
For example:
The movie was bestial.
This sounds unnatural unless a very specific context supports it.
Instead:
The movie was terrible.
Use bestial when you want to communicate something savage, beast-like, brutal, or inhuman.

Final Thoughts
When I first look at a word like bestial, I find that connecting it to its root makes the meaning much easier to remember.
Think:
Beast → bestial
Something bestial can resemble a beast physically or behaviorally.
But when the word describes human actions, it usually goes further. It suggests something savage, brutal, cruel, or lacking normal human compassion.
Compare these two examples:
A bestial creature appeared from the cave.
Here, bestial means beast-like.
The prisoners were subjected to bestial treatment.
Here, bestial means extremely cruel or inhuman.
That’s the distinction I would keep in mind whenever I encounter this word.
Also remember that bestial is a formal and strongly negative adjective. It isn’t simply a more sophisticated way to say “bad.” Use it when you want to communicate a particular idea of savagery, brutality, or beast-like behavior.
Wrap-Up
The easiest way to remember bestial is through three ideas:
Bestial = Beast-like
The creature had a bestial appearance.
Bestial = Savage or brutal
The attack was bestial.
Bestial = Cruel or inhuman
The prisoners suffered bestial treatment.
From a grammar perspective, remember that bestial is an adjective. It can come before a noun:
bestial behavior
bestial cruelty
bestial treatment
bestial attack
Or after a linking verb:
His behavior was bestial.
The creature looked bestial.
If you’re learning English vocabulary, I recommend learning bestial together with its common collocations rather than memorizing the dictionary definition alone. Words such as “bestial cruelty,” “bestial acts,” “bestial behavior,” and “bestial treatment” will help you recognize how native and proficient English writers actually use the word.
Most importantly, pay attention to context. If bestial describes a creature, appearance, or sound, it may simply mean beast-like. If it describes human behavior, treatment, or actions, it usually carries the much stronger meaning of cruel, savage, or inhuman.
Once you understand that difference, “bestial” becomes a much easier word to recognize, understand, and use confidently.
