When I was little and I heard someone describe a bath as ‘lukewarm’, I totally thought it had something to do with Luke Skywalker. You’ll be sad to hear that, unfortunately, it doesn’t.
You know what ‘lukewarm’ means – something (usually liquid or food) that’s not very hot. The ‘warm’ bit means ‘warm’, obviously (and doesn’t have very interesting etymology – it comes from the old German word… wait for it… ‘warm’). But what about the ‘luke’ part?

Well, we can trace that all the way back to the proto-Germanic (obviously you’re far too clever for me to need to explain what that means) word ‘hlēwaz’, which also means ‘warm’. Old English then nicked it in and used it for (again) ‘warm’. ‘hlēwaz’ then morphed into ‘lew’, ‘lewk’ or ‘leuk’ in Middle English, which meant ‘tepid’ (or ‘slightly warm’), which then, through the magic of language, became the ‘luke’ we know today.
You’ll be noticing a theme here. All the words I’ve mentioned, including ‘luke’, mean ‘warm’. So ‘lukewarm’ means ‘warm warm’. This makes it on a par with saying LCD display (liquid crystal display display) or PIN number (personal identification number number).
