Hi,

I don't know the phrase 'out of form'. The expression 'out of sorts' is the accepted one suggesting that there is something wrong with you but it isn't very serious.

Hi,

'Out of order' refers to things like machines and means they do not work. You could go to a ticket machine to pay for your car park and there would be a notice with the words: 'Out of order' and that means you can't use that machine because it's broken.

Hi,

Why "out of trend" is incorrect?
"He didn't look well" means he was sick or he wore badly?

Thanks.
