What is the difference between except and except for?

Well, Bubu, I will quote Swan for you:

(1) We use 'except (for)' for general statements, especially after generalizing words like all, every, any, no, whole, etc:

I ate all my salad except the jalapeños.
I ate every bit of my salad except for the jalapeños.

(2) In other cases, we usually use 'except for':

I ate my salad except for the jalapeños.

(3) We use 'except' before prepositions and conjunctions:

There were jalapeños everywhere except in my salad.
I like jalapeños except when they are in my salad.

(4) Before an infinitive, we use 'except', while before an -ing form we use 'except for':

I will do anything except eat jalapeños
I enjoy doing anything except for eating jalapeños

This being quoted, I think that in the cases of (2), (3) and (4), both forms are actually used in the spoken language.
Oh ! So, meaning-wise, there is basically no difference between the two.

Can I say that ALL the sentences with "except for" are identical to the ones with "except" , except for some words like 'all', 'no', 'every'....?

Hope I am correct.

Shouldn't it be except FOR in (4) like he said himself? - before -ing comes EXCEPT FOR
Yes, I got a little confused typing all those excepts and fors-- so I'll fix it in my post and add (4) to the exceptions. Thanks, Mav.
As far as the meanings, Bubu, 'ALL the sentences with "except for" are identical to the ones with "except" ', as far as I can see.

Hallo Mister Micawber,

Do you also answer questions in another site called 'able to know .com'? I found the same id 'Mister Micawber' there too, and with a photograph.

I am only a bit curious.

Merry Christmass to you and a happy new year.
That's me, Bubo. English Forums is my prime concern, but I am ubiquitous-- there is no escape!

Happy Holidays to you too.
