Usage

When ago is followed by a clause, the clause is normally introduced by that rather than since: it was sixty years ago that I left this place (not it was sixty years ago since I left this place). The use of since is redundant and is not correct in standard English

Origin

Middle English ago, agone, past participle of the obsolete verb ago ‘pass’, used to express passage of time.

Pronunciation
