Using correct grammar and punctuation is kind of a big deal to me. When I write things, even my typo-ridden tweets, I take grammar and punctuation rules into account. I usually won’t write it if I don’t have a rule to back it up (even the wrong rule, apparently). This week’s debate?
I have been against couple’s shower all along. I knew it wasn’t a shower belonging to one couple, despite the choices invitation websites are full of. However, I would have laid my life down (or probably not) backing couples’ shower as correct; I have an email account full of planning correspondence to prove it. Thought process? It is a shower that belongs to the couples (plural) being invited.
The better answer? It’s a couples shower. Couples is being used as a descriptor, rather than a possessive. Couples is describing the type of shower. It’s a shower for couples to attend.
If you need me, I’ll be rethinking my apostrophe usage–and emailing my invitation designer.
