first class

Hi,
"I have always posted my letter first class, although it costs more."
Please tell me the function of “first class” in the context?
Does it consider as an adverb modifying the verb “posted”?
Thank you very much.

Yes, and it usually means "express/priority mail." 👁 Smile :)

Thank you comsci very much for your help and for giving me some new words.
In this case, a noun plays the role of an adverb.
Could you please give an example with the same situation.
Thank you very much.

Where have you been, Mimi? Nichec told me you had developed a taste for patisserie, but I don't believe it.

I suppose it must modify posted because there is no other verb. A first class letter is given priority and arrives sooner than a second class one, unless the distances are very short. You put an expensive stamp on a first class letter. Obviously the actions of posting a first class and second class letter are the same; it's not as though you put a first class letter into the box with a special sort of reverence, so I think your sentence is poor English: the effect is ridiculous. We'd say more naturally I always send my letters first class - the act of sending includes choosing an appropriate stamp, so that can suitably be qualified by first class.

At the end of your last post you asked for some examples of other uses of first class as an adverb. I can't think of any, which doesn't mean there are not plenty. In the case of a letter, first class is a technical term, which wouldn't appropriately apply in another context, except perhaps on the railways, where one can travel first class.

Dear Thomas Tompion,
Believe one thing, wherever I go, I return to my home.
You made me laugh – I admitted I ate two cakes at the same time but it was in a dilemma. Believe me I never get fat.
Please tell me if "first class" could be placed in different positions.
1. I have always posted my letter first class, although it costs more.
2. I have always posted my first class letter, although it costs more.
In the first sentence, "first class" is considered as an adverb, what about the second one? Is it an adjective? Or "first class" in the first sentence also an adjective modifying the nound "letter"?
I feel confused now.
Thanks.

In your first sentence, I believe that "first class" is an adverb modifying the verb posted. It would be the same as saying "I always travel first class when I fly."

In your second sentence, "first class" would be an adjective describing "letter" so this sentence doesn't work, Mimi. What it is saying is that you've always posted your first class letter (which makes no sense).

Dear Dimcl.
But if I say, "A first class letter goes faster than a second class
letter", is it correct?
Does it mean "a first class letter" is correct but not in my second sentence?
Thank you very much.

Yes, the way you're using it here is correct. "First-class" is an adjective modifying "letter" so you're describing the difference between first-class letters and second-class letters. In your previous sentence ("I have always posted my first-class letter, although it costs more.") it's still an adjective modifying "letter" but its use this way isn't logical. Forget the part about the price - if you don't worry about the cost, what you're saying is "I always post my first-class letter". Well, of course you post it - what else would you do with it?👁 Smile :)

My dear Dimcl.
Thank you for helping me.
You explained to me with all your heart.
Thanks.
