Salut tout le monde! Hello everyone!
I thought it would be good to compile a list of alternative (including slang) words for body parts - starting with the head, working downwards and including insides + organs as well. I have chosen not to include gender-specific parts) I thought if somebody French came over and heard people talking about the barnet or the ticker they'd be totally stumped! I imagine possibly some American English speakers too? Please remember this is from a British English speaker!
OK here goes
Hair - cheveux
alternative words: tresses, locks, barnet
(usage - tresses and locks are quite romantic and poetic words, not likely that they'd be used in everyday speech. Barnet is slang, my mother used to shout "have you brushed your barnet?!" It's a bit Londoner sounding, even though she's not from there, Hmmm.)
Head - tête
Other words: Noggin (no idea where this one came from!!) and loaf - you may hear people saying "Use yer loaf" as in "Use your loaf of bread", which is cockney rhyming slang for head, also "bonce"
Face - visage
mug, mush (ugly words, for a non-nice way of talking about your face. mush is pronounced like push or cushion NOT like lush or much, otherwise it means a puréed substance)
Ears - oreilles
Alternatives: lugs/lugholes quite a disgusting word. But if you hear it, now you know what it means.
Eyes - yeux
Nose - nez
slang words: conk, schnozzle/schnozz, hooter
Mouth - bouche
slang words: trap (often used offensively - shut yer trap!), gob (also used offensively in the same way as trap) I believe people also say cakehole or piehole, personally I don't. I think it's used in the same way
Teeth - dents
slang: gnashers, toothypegs/pegs/peggles (childish - are these only used by my mum? lol)
Heart - coeur
slang: ticker (as in the old ticker's still going strong, he's got a dodgy ticker - not an affectionate or romantic word!!)
Stomach - estomac
Navel - nombril
belly button/ tummy button
Intestines - intestin
Bottom - derrière
other words: buttocks, posterior (elevated language),
behind, backside, butt (slang),
), botty (lol- a bit childish) arse - rude
Feet - pieds
slang: tootsies (after a hard day's shopping - oh my poor little tootsies!!)
Some slang words are just abbreviations - so here are a few to look/hear out for. Lashes = eyelashes, brows = eyebrows, 'pits = armpits.
Et voilà! I'm sure there are more and some very different ones according to age/region/country. I am looking forward to hearing about your french alternatives!
