We never say a women's anything in English! You need woman for the singular noun.
They do in retail jargon, but in general you are correct.
If I hear "a woman's coat" I think it's a coat belonging to a woman. "A women's coat" means a coat meant for women, not for men. How else would you say it, if you say "women's coat" sounds unnatural to you? Thanks!
Women's coats (plural). One coat belongs to one woman, but a group of coats can be a category.
Runners should be as good as sneakers here, different varieties of English.
Agree. We use the term 'runners' & 'smeakers'. 'Trainers' can also mean a 'baby's diapers'!!
How come this section always reports a typo when it comes to the word "women's" in possessive form. Yet even when using hints, the app provides nothing more.
