Dirty, Filthy, Messy? What’s the Difference?

Do you know the difference between dirty, filthy and messy? These three adjectives are often confused, but they do not mean exactly the same thing. In this lesson, you’ll learn when to use dirty, filthy and messy, see clear examples, compare their meanings and practise them in a short quiz.

All three words can describe something that doesn’t look very nice, but they don’t mean exactly the same thing.

Compare:

• Your shoes are dirty. → They need cleaning.
• Your shoes are filthy. → They are extremely dirty.
• Your room is messy. → Things are untidy and out of place.

Let’s look at the difference.

Dirty

Dirty means  not clean. Something may have dust, mud, grease, food or another unwanted substance on it.

It is the most common and neutral of the three words.

• Your hands are dirty. Go and wash them before dinner.
• The kitchen floor gets dirty very quickly when it rains.
• After the football match, the players were sweaty and dirty.
• The windows are dirty. We should clean them.
• I don’t like swimming in dirty water.

We commonly talk about:

dirty clothes, dirty dishes, dirty hands, dirty shoes, dirty floors, dirty windows

Remember: If something is dirty, it needs cleaning.

Filthy

Filthy means extremely dirty.

It is much stronger than dirty and often suggests that something is unpleasant or disgusting.

Compare:

• My shoes are dirty.
• My shoes are absolutely filthy!

• After a week of camping, we were filthy from head to toe.
• She wouldn’t use the towel because it looked filthy.

• The old mattress was filthy, covered in stains and dust.

We often use absolutely with filthy:

• Look at your trousers! They’re absolutely filthy!

Remember: Filthy is much stronger than dirty.

Messy

Messy means untidy or disorganised.

The important thing to remember is that something can be messy without being dirty.

For example, a bedroom may have books, clothes and papers everywhere, but everything may still be perfectly clean.

• Your desk is so messy. How do you find anything?
• The children’s room was messy after they finished playing.
• His handwriting is messy, but I can still read it.
• I can’t concentrate in a messy environment.

Messy can also be figurative

We can use messy to describe a complicated or unpleasant situation:

• The divorce turned into a messy legal battle.
• The situation became rather messy.
• They had a messy breakup.
