Difference Between Just and Only

Main Difference – Just vs Only

Just and only are two adverbs that are interchangeable. However, it is important to notice that just and only are interchangeable only in some instances. In some cases, the interchange of these two adverbs may result in a distortion of meaning. The main difference between just and only is that just can mean exactly whereas only does not carry this meaning.

Just – Meaning

As an adverb, just has many meanings. It’s better to look at these meanings before going straight to the difference between just and only. Given below are some basic meanings of just.


That’s just what he said.

This is just what I needed.

He’s a human being, just like everyone else.

Very recently:

I just got a call from the office.

I just finished my dinner.

I heard about it just now.

Simply, no more than:

Calm down – it was just a nightmare.

They were just interested in the scenery.

He just cares about his looks.

When we are using just in a sentence, the word order or the position of just in the sentence is important. This is because a change in position can result in a change in meaning. For example,

He just had two pieces of cake – This implies that he had cake recently.

He had just two pieces of cake – This implies that he had only two pieces.

It is this latter meaning of just that makes just and only interchangeably. The third meaning of just, explained above (Simply, no more than) is similar to that of only. Therefore, only can be used to replace the above three examples:

Calm down – it was just a dream.→ Calm down – it was only a dream.

They were just interested in the scenery. → They were only interested in the scenery.

He just cares about his looks. → He only cares about his looks.
