Should have or should of?

[HeyJude07]

Because I have no idea.

Sorry if this has been done before.

Should have.

should have

Thanks, embarrasingly I tend to use should of more.

Should have. Should is an auxiliary and requires a verb to follow. Of is not a verb!

Think "of" is a misunderstanding of the contracted form "should've". that said, I think Keats used "should of"!

Try taking the should out if you're doubting yourself.

I.e. "I should have/of cleaned the car."

vs.

"I have/of cleaned the car."

Since I don't believe I've ever heard someone say "I of cleaned the car" I think it's possibly a good way to remember

shoudl have,
there are so many should of s on mumsnet it is so annoying,
and otehrs,
fed up of for example

"fed up of"? Not sure what's wrong with that...

fed up with it should be
i am fed up with this house,
not not fed up of this house for example.

should have
fed up with?

But what about "I'm fed up of having to clean up after you?". I don't have a problem with that - maybe a regional variant?

Cross post ScareyBitchFeast
Was fairly sure it was fed up with hence the ?

it's "i'm fed up with having to clean up after you"

it doesn't change

Nope, I'm with habbibu on this one. 'Fed up of' is accceptable too.

And my dictionary agrees.

should have

fed up with

Looks like it may be a modern variant - see here!

Should have, or Should've. Never should of.

prefer fed up with, but i may do of, I have no idea

Should have.

I think I do both, tbh.

Oooh, Should have, would have, could have!!
Fed up with/of I use both.....mmmm.
However in the west country we say snow pitches, not settles.

Just had a look at my mega-corpus; 'fed up of' has 18 pages of citations, 'fed up with' has 300ish pages. So 'fed up with' the standard form, but 'fed up of' perfectly acceptable.

Unlike should of which is plain wrong, ungrammatical nonsense.

Like Dr Wordsmith though habbibu - never seen that before.

Just looked at OED - originally: Slang phr. to be fed up: to be surfeited or disgusted (with), bored or tired to breaking-point. So fed-up a. Also with emphasizing expressions, as fed to the (back) teeth, fed to death. Also without up.

So it's quite interesting - you can say "fed up with" - meaning full to the brim, stuffed, had too much of - yet we say "full of beans", using "of" in a similar way. One of the joyous inconsistencies of English.

Any takers for:

Fed up by your behaviour?

Fed up at having to clean up after you?

And of couse should have/ should've...

I'm thinking that as "fed up" is slang anyway there is no point in being pedantic about it. Also interesting in OED def. is that it was quite often used without the "up", viz:
1921 WODEHOUSE Indiscretions of Archie i. 11 I've never done anything much in England, and I fancy the family were getting a bit fed.

1922 A. S. M. HUTCHINSON This Freedom IV. iv. 293 Oh, those sickening scarves and things, they were eternally knitting, that wasn't war work. It was fun at first. They were fed to death with doing them now.

1928 Strand Mag. July 4 Her aspect was that of a girl who is fed to the teeth.

It's either an idiom or colloquialism, not slang...
