Hello dear all,
In my Grammar book it's written that:
An apostrophe (') is sometimes used before the S in the plurals of abbreviations.
MP's, CD's OR (more often) MPs, CDs.
This is my question: If MP's, CD's are correct then can we say that Friends=Friend's?
I mean, as you know, the plural form of Friend, is Friends. Then according to the above explanation, can we say that
the plural form of Friend can also be Friend's or only Friends is correct?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
The meaning is clear with CDs, MPs, 1980s, LEDs, etc. However, there is a problem with lower case letters, as in: There are four i's in "Mississippi". Without the apostrophe, it would be: There are four is in "Mississippi", with is spelling the word "is". This convention does not apply to regular words.
