Word Choice: Began vs. Begun

They are similar in spelling, but what exactly is the difference between the words ‘began’ and ‘begun’? Both stem from the verb ‘begin’, but they have specific uses. Read on to learn more about how they should be used.


The word ‘began’ is the simple past tense of ‘begin’, which means ‘start’. ‘Began’ is therefore used to describe things which happened in the past:

I began to run just as the bus pulled away.

However, ‘began’ is never used with auxiliary verbs (i.e. verbs, such as ‘has’ or ‘would have’, that add additional information to another verb in a sentence).


The word ‘begun’ is the past participle of ‘begin’. ‘Begun’ is used in the perfect tense sentences. It is, therefore, incorrect to write ‘I begun’, as ‘begun’ can never be used without an auxiliary verb (‘has’, ‘have’ or ‘had’). Thus, we must say that something ‘has begun’ or ‘had begun’.

The auxiliary verb used with ‘begun’ affects the tense of the sentence. When combined with ‘has’ or ‘have’, it is part of the present perfect tense. Typically, this shows that something started in the past and continues in the present:

I have begun writing my novel.

When combined with ‘has’, ‘begun’ is part of the past perfect tense. This is typically used when describing a completed action in relation to another event:

I had begun to write when my computer died.

The auxiliary verb and past participle in sentences like these can sometimes be separated by a negative, such as ‘not’ or ‘cannot’, as in the following:

I have not begun to write my essay yet.

The Difference

The difference between ‘began’ and ‘begun’ is a matter of tense. Remember that the simple past tense (‘began’) does not require an auxiliary verb, while the past participle (‘begun’) always needs one.

I have began attending art classes.Incorrect 

I have begun attending art classes.Correct

I begun dancing when I was three years old.Incorrect

I began dancing when I was three years old.Correct

what about Well begun is half done
    22nd May 2018 at 10:50
    Hi, Vinayak. Could you clarify what you intend by 'well begun is half done'? If you can, we can try to make some grammatical recommendations.

      I'm sure Vinayak was asking about the well-known proverb "Well begun is half done." and was wondering why it didn't follow these rules. My assumption as to an answer to his question is that since the proverb is very old (referred to by Aristotle) we're probably looking at a translation issue. More than likely, when translating into English, the word begun was used because of it rhyming with done in an attempt to make the proverb easier to remember.

      Ah, apologies. Didn't know the phrase until now! Translation might be part of the issue, but more important is that it's not meant to be a full grammatical sentence. If you unpack it, it would be something like 'Something that has begun well is half way to completion', which fits the rules above.

Let the Journey begun
    24th May 2018 at 10:11
    Hi there. The correct phrasing there would be 'Let the journey begin'.

Hi! I think what Vinayak meant to ask was like in the case of 'well done'. I think the statement is correct. He only needed more explanation to help him understand it. I really don't have one now, so, don't ask me. Thanks!

What about The holidays have began ...
    2nd July 2018 at 09:07
    Hi, Debra. That should be either 'the holidays have begun' (present perfect tense) or 'the holidays began' (simple past tense).

Befor e and after the storm begun. Stella’s face says it all.
    23rd July 2018 at 08:58
    Hi, Jordan. 'Begun' is a past participle, so it should be combined with a helper verb (e.g. 'had begun'). We're not sure whether 'began' or 'begun' fit in that sentence as it stands, though, since 'says' is the present tense (you've also got a sentence fragment in the first clause there). You could say, 'Before and after the storm began, Stella's face said it all.'

"Program is begun" or "progarm has begun" which sentence is correct .
    2nd August 2018 at 11:26
    Hi, Vivek. 'Is' is a present tense verb, so it cannot be used with the past participle 'begun'. The correct phrase would therefore be 'the program has begun'. However, keep in mind too that British English only uses 'program' for computer programs. In any other context, it would be 'programme' instead.

?What about 'The adventure just began.' Is it correct?
    22nd August 2018 at 14:36
    Hi, there. Yes, 'The adventure just began' is grammatically correct (simple past tense).

"Cleanup efforts begun in the 1990s are ongoing" Is that correct?
    1st February 2019 at 08:53
    Hi, Zoe. As mentioned in our post, 'begun' is a past participle, so it is always preceded by 'has', 'have' or 'had'. Your sentence needs 'began', and it should read as follows: 'Clean-up efforts that began in the 1990s are ongoing.'

So which is CVV perfect?...I'm over today and it hasn't even begun/began?
    13th March 2019 at 12:33
    Hi, April. As mentioned in the post, if you have a helper verb such as 'has' (in your case, as part of 'hasn't') in your sentence, you will need the past participle. So your sentence should read 'I’m over today and it hasn’t even begun.'

I began studying english but i felt there is no improvement.
    22nd July 2019 at 08:03
    Hi, May. The use of 'began' there is fine, but the overall sentence is a little confusing. Should there be a period of time included? E.g., 'I began studying English [two weeks ago], but I do not feel I have improved since then.'

officially began on or officially begun on?
    22nd August 2019 at 08:35
    Hi, Laura. It depends on the tense of the sentence (e.g. 'It officially began on...' would be the simple past tense, but 'It will have officially begun...' would be the future perfect tense). Check the blog post for advice on when to use each term.

Is the sentence “Jake and his dad have begun their journey.” correct?? I’m from Germany and i’m a little confused.
    25th September 2019 at 08:21
    Hi, Sofia. The sentence is in the present perfect tense, so the past participle form 'begun' is correct, yes.
27th September 2019 at 05:39
Which one is correct? It just Begun or it just Began or it just Begin ???
    27th September 2019 at 08:25
    Hi, Naha. Depending on the tense of the sentence, it would have to be 'it just began', 'it has just begun' or 'it is just beginning'.
