Could any one please correct my sentence as follow,
" we require payment when your purchase has been made"
" we require payment when purchase made"
what tense of verb do I use after "when"
Could anyone please explain to me what the tense should be after "when"?
‘When’ can be used as an adverb, conjunction, pronoun and noun. Its common use is adverb or conjunction. It can modify a verb or join another clause in any tense depending on the context.
Let us take its use as adverb which describes: at what time or period? how long ago? how soon
When are they expected?
When did you come to office today?
When will this work be completed.
Similarly as conjunction, any tense is possible
He will leave the place when the rain stops
I visited the place when I was young.
You can not force me stay in this place when I will be a doctor.
