#GRAMMARTRIVIA: The use of ‘When I + Simple Form’ and ‘When I have + Past Participle’

Howdy, fellas! How’s everything going? I hope it’s going great!

Anyway, I’d like to discuss the use of ‘When I + Simple Form’ and ‘When I have + Past Participle’. Here we go! #GrammarTrivia

First of all, study this example. A: What time will you phone me tomorrow? | B: I’ll phone you WHEN I GET home from work. #GrammarTrivia

“I’ll phone you when I get home from work” is a sentence with two parts, which are: ‘the main part’ and ‘the when-part’. #GrammarTrivia

The main part of the sentence is ‘I’ll phone you’. Meanwhile, the when-part is ‘when I get home from work (tomorrow)’ #GrammarTrivia

The time in the sentence is future (‘tomorrow’) but we use a present tense (‘get’) in ‘the when-part’ of the sentence. #GrammarTrivia

Remember that we do NOT use ‘will’ in ‘the when-part’. Study the following examples. #GrammarTrivia

“We will get out WHEN IT STOPS raining.” (NOT ‘when it will stop raining’). #GrammarTrivia

“WHEN YOU ARE in London again, you must come and see us.” (NOT ‘when you will be’). #GrammarTrivia

“What do you want to be WHEN YOU GROW UP?” (NOT ‘when you will grow up’). #GrammarTrivia

The same thing happens after: while, before, after, as soon as, until, etc. #GrammarTrivia

Example: “I’m going to read a lot of books WHILE I AM on holiday.” (NOT ‘while I will be’). #GrammarTrivia

Further, you can use the present perfect (have + Past Participle) after when / after / until / as soon as. #GrammarTrivia

Example 1: “Can I borrow that book WHEN YOU HAVE FINISHED reading it?” #GrammarTrivia

Example 2: “Don’t say anything while Brian is here. Wait UNTIL HE HAS GONE.” #GrammarTrivia

But DO not use present perfect (have + Past Participle) if two things HAPPEN TOGETHER. Compare the examples. #GrammarTrivia

“When I HAVE PHONED Kate, we can have dinner.” (First I’ll phone Kate and after that we can have a dinner.) #GrammarTrivia

But, “When I PHONE KATE this evening, I’ll invite her to the party.” (NOT ‘when I’ve phoned’). #GrammarTrivia

Therefore, that’s how we use of ‘When I + Simple Form’ and ‘When I have + Past Participle’. You get the point, don’t you? ;) #GrammarTrivia
