When we use "welcome" and "welcomed"

[Steve88]

I wish to find out is it correct to say,'The headmaster welcomed all the students' or " The headmaster welcome all the students"

[Mister Micawber]

.
Use 'welcomed' or 'welcomes' here.

Excuse me, is "welcomed" the past of the verb "welcome" and is "welcome" the past participle of it?

Many thanks
Nessie

No, the past participle of the verb 'welcome' is 'welcomed'.
However, the word 'welcome' also functions as an adjective.
.

[Nessie]

So the word "welcome" in this sentence is an adjective and not a past participle?

You're welcome.

.
The past participle ends in -ed.

Thanks a lot, MM. But could you please explain more about the sentence "you're welcome"? why isn't it "you're welcomed"?
Many thanks

The word welcome is an adjective in the expression You're welcome.

Perhaps if you try to write a few sentences of your own using the past tense of the verb welcome (welcomed) in the active voice you will begin to see a difference, Nessie.

[Nessie]

She welcomed us to her house
We've welcomed the newcomers to our school very warmly

They are welcomed to the country

=> I still see no difference, Amy, what exactly do you mean?

But... Amy, why do you want me to answer those questions? may be I'm so dumb (+_+) but how do they relate to our original matter?

Besides, the questions are a bit too specific and because it isn't mentioned in the sentences, then how can we know exactly how "she" welcomed "us" or how "we" welcomed "the newcomers" or how "they" are "welcomed" and by whom?

I know you don't ask me to do this just for the sake of the answers of those questions, but what do you imply?

I had been hoping you would use your imagination to supply some details about how one person might go about welcoming another person, Nessie.

The point is that the verb 'to welcome' involves action and there are a variety of things you might do in order to welcome someone.
.

[Nessie]

I still don't understand, Amy. Surely I know there are a variety of things we can do to welcome someone, and if you want, I can imagine some of these things, but how is it related to our original matter, which is the difference between the use of "welcome" as a adjective in the sentence "you're welcome" and the use of "welcomed" as a past participle in the sentence "you're welcomed"?

Many thanks
Nessie
