Lewd, licentious

[benjaminlee]

His mouth is full of lewd words. And indeed he is a lewd man. (self-made)
I know that “lewd” can be used to modify words or behavior, but can I just say “a lewd man” to mean "a licentious man"?

You can describe someone as a "lewd man", but lewd does not have the same meaning as licentious.
