I have always thought plurals in English is always word + s (except for irregular plurals). In my language we use apostrophes when a word ends in a vowel. I have been correcting my friends who write line's
instead of lines
.
About a week ago I went to the UK. I noticed advertising boards with phrases that do use apostrophes in plurals. No, this was not like The cat's leaping
as in The cat is leaping
but something along the lines of We sell car's
.
I am very confused now, can anyone explain this to me please?
