As the summer vacation season draws to a close, we hear about a new entry in the "X-cation" trend from Stan Carey, a professional editor from Ireland who writes entertainingly about the English language on his blog Sentence First.

The portmanteau word staycation is here to stay, it seems. Even in Ireland, where we say holiday(s) rather than vacation, staycation (stay + vacation) has established its niche sense of a holiday at home, near home, or at least somewhere on the island. It still sounds new or awkward to some people, but it's been around a while: Word Spy has a citation from 2003, while Ben Zimmer found a hyphenated use from May 1999.

A daycation is similar, but happens in one day; see Macmillan Dictionary's article for more, including greycation and naycation. Last week's Galway Advertiser has a related blend that's new to me: selfcation, a self-catering holiday or self-catering vacation, presumably formed by combining self-catering with vacation (with a neatly overlapping /keː/).

Out of context, you'd be forgiven for thinking a selfcation might mean a holiday from oneself (cf. me-cation, a holiday for oneself), but the text makes its meaning clear. Here's selfcation used in the article 'Ten ways to enjoy a staycation in Ireland':

Why not go on a selfcation and hit the sunny south east where there is a wide range of self-catering accommodation perfect for families who want to relax in the comfort of a home away from home. [surrounding text]

Maybe selfcation has been doing the rounds in travel writing, but this is the first time I've come across it, and it appears to be a recent coinage. Not only is there no entry at the Urban Dictionary — not yet, anyway — but there's hardly any mention of selfcation anywhere online. Most of Google's results for selfcation relate to cations, positively charged chemical ions(from Greek kata, down, + ions).

There's a reference here (2001) to 'selfcated flats', but I don't think this has anything directly to do with vacation or selfcation; it's just a misspelling of, or shorthand for, selfcatered, i.e. self-catering:

Have you heard selfcation before? What do you think of it? Is it superfluous, unsightly, unobjectionable, useful, welcome?
