Is there one word that by itself means the inability to recall when something happened (or anything, for that matter)?
For example, if I am asked to respond to the question, "What date did your child lose her first tooth?" and I can't remember and want to respond to the question with only one word, is there a word that fills the bill? The questioner will understand that I cannot answer because I can't remember?
The only word I can think of is 'forgot.' I'd like to know if there are others.
I am not looking for a psychology term like repressed-memory, or anything else pop-science like that, but merely one word that means I can't recall.
