Continually And Continuously Are Similar Yet Not The Same

Continually And Continuously

Continuously and continually are two very similar adverbs. However, there is a subtle difference between the meanings of the two words.

Continuously means without interruption, whereas continually indicates repeatedly or at regular intervals.

In many situations, you could use either one. It would make little difference to your readers.

It’s not a classic grammar mistake. However, if you want to ensure you use the correct word, it helps to understand the slight difference between the meanings.

The difference between continually and continuously

When we say that something happens continually, it means repeatedly, over and over again, or frequently.

Continuously, on the other hand, refers to an action that is ongoing, unbroken, or non-stop.

It might not seem like a lot of difference. But in some contexts, you might want to think about which one to use.

Let’s look at a couple of quick examples.

Even when he’s on holiday, Michael continuously checks his work emails. Wrong

In this sense, it would mean that Michael does nothing else except check his emails.

Even when he’s on holiday, Michael continually checks his work emails. Correct

Now, it’s correct because it says that Michael regularly checks his emails.

It doesn’t say how often, but it could mean once, twice, or a few times a day.

The easy way to make the right choice is to decide if the action is always or frequent.

Choosing between continual and continuous

Continual and continuous are the adjective forms of continually and continuously.

They share the same meaning, but they describe nouns instead of defining an action.

You would rarely need to, but it is possible.

You can modify the two words in a similar way that you would grade a word, such as always with nearly or almost.

The doctor is almost/nearly always late for his appointments.

Almost/nearly continuous rain ruined our holiday.

The almost/nearly continual messages were a distraction we could have done without.


Are constant and constantly the same?

They are similar but not quite the same.

When we use these two words, they say that it is a repeated action like continually.

But the difference in meaning is that the result of the action is always the same.

Sometimes, it is about negative results.

But it can also have positive uses.
