Hi,
the two words, that are added the most to the personal dictionary of Spanish users are “pm” and “am”.
I believe “am” and “pm” are widely used but correct spelling would be “a.m.” or “p.m.”.
However, LT doesn’t suggest “a.m.” or “p.m.”:
The only helpful source I found is:
If “p.m.” is valid, then we should suggest it.
What do you think?
