@WBYeats,
Quote:[It's] The voice was so clear that I was able to recognise the indefinite article A, but in English, [don't] do we [n]ever use A for LEAVE?
When it's 'leave' in the sense of a "leave of absence" we always do use 'a', WB.
eg He was absent without leave.
eg The court granted him leave to appeal against the sentence.
eg She asked for
a leave of absence to attend a funeral.
The first two are not the same as 'leave of absence'. The third needs 'a'.
