What is the proper way to use word unwelcome or unwelcome?

"Unwelcome" is an adjective, so it describes a noun. Here are some examples:

* "His comments were unwelcome." (Unwelcome describes the comments.)

* "The stranger's presence was unwelcome." (Unwelcome describes the presence.)

* "The dog's barking was unwelcome." (Unwelcome describes the barking.)

"Unwelcome" is not a verb, so you can't say something like "He unwelcome her." You could say:

* "He made her feel unwelcome."

* "He rejected her unwelcome advances."

"Unwelcomed" is an archaic past participle of "unwelcome." It is very rarely used in modern English.

Hopefully, this clarifies the correct usage of "unwelcome"!
