Not quite Pedants Corner, but perhaps worth a ponder?

My (now deceased) Uncle Ronnie, usually added ‘what’ at the end of his sentences.

‘Shall we have a drink, what?’ Or as he enjoyed my mother’s cooking he would say ‘Delicious lunch, what’.

You never hear people use the word ‘what’ in that way, nowadays.

Chums; I have a friend, late eighties, who uses it regularly.

Cove, meaning a person. Always used by my husband (public school) and guinea gold, to describe a truly good person.

Gordon Bennet! I don’t hear that expression so much these days.
My grandmother would not allow me to say Blimey! because she associated it with Blind Me.

Not on your nelly, was used in Glasgow too.

Not on your nelly.
Or was that just a London thing?

I remember the other girls laughing at school at a new girl who had just arrived and saying something was "jolly splendid"!

So that was infra dig already back in the 60s.

My mother always said "Perish the day". . I haven't heard that in a long while.
She also told us about ' Crikey etc Bradfordlass, and we were not allowed to say them. Though my Dad often said " Crikey Moses".
I had a friend who shouted " Horlicks" when she was cross. Very effective.

FarNorth Being pedantic here.

I can't see any reason why 'gay' cannot mean both happy and homosexual in context.

After all, the word 'book' has many different meanings. Likewise: bat, key, try, push, card etc., so why not 'gay'?

“Bristol bright”, toffs, dosh

I use quite a few of those words, sometimes not entirely seriously.

I'm listening to an audiobook just now, set in the 40s, where people have been described as being quite gay.

Ngaio1 and CherryCezzy I still use a lot of those words and I certainly didn't go to public school.

Many years (40) ago I read that expressions such as 'Crikey', 'Blimey' and 'Struth' come originally from people swearing informal oaths to confirm they were telling the truth.

'Crikey' - may Christ kill me if I'm lying.
'Blimey' - may God blind me if I'm lying.
'Streuth' - that is God's truth.

I'd be interested to know if others have heard this. There's a lot on the Internet but most is unreliable.

Yikes
Blimey
Toodle do (not sure that’s the accurate spelling)
Harlot
Twerp
Noggin

Oh. I use lots of these words. I model myself on the aunts that Mr PG Wodehouse writes about so splendidly don't you know.

Goodo! My DIL 's mother says frightfully

Ha ha! I use lots of these words I'm afraid.
Showing my age, obviously. Though my youngest daughter uses quote a few too and she's only 30!

Fit as a flea!

My German friend had never heard it before despite living here for 50 years

A Billy Bunter expression Phoenix think its crikey though.

Oh dear! I still use beastly, ghastly jolly, smashing, splendid, chap, chums and Oh my giddy Aunt! Several friends (chums) do likewise.

I still use jolly, and gosh, (but not together) and crickey! (that doesn't look as though it's spelled right?)
