Longsleeve shirt, long sleeve shirt, or long-sleeved shirt?

Question

Hello: Is it longsleeve shirt? long sleeve shirt? Or long-sleeved shirt? It's so confusing.

Answer 1

I agree, it is confusing. It appears that the proper term is "long sleeve shirt."

My research method is embarrassingly simple but I'll share it so you can use it, too, in future. I started typing "long sleeve" into Google and a lot of advertisements came up for "long sleeve shirts." See my Google Search Results.

Since--for the sake of marketing--ads seek to appeal to public opinion and public good-taste, they use the correct and proper term. For this reason, I conclude that the correct term is "long sleeve shirt."

EDIT: This must be one of the words that has more than one correct spelling. In the comments below, Kate Bunting gives me a Cambridge Dictionary reference for another spelling: long-sleeved.

The word is defined as being an adjective to mean "having long sleeves: a long-sleeved T-shirt." Its opposite is given as being "short-sleeved."

Answer 2

Ads very rarely get it right. They're looking for what looks visually appealing on a sign, not what is correct. long-sleeved is correct.
