"I've already told you three times that I'm not coming!"
An intensifier used to emphasize impatience or express exasperation.
In plain English: Already means something has happened sooner than expected or before now.
"I have already finished my homework for today."
The word already comes from Middle English alredy, which originally meant "fully" or "completely." It was formed by combining the prefix al- with the word ready to indicate that an action had been completed in advance.
