In my textbook, there's a chapter on conditional relative clauses, in which it explains how relative pronouns and adverbs, especially when they are indefinite, can form the protasis of a conditional statement.
Whoever has a sword and shield should help protect the wall.
In the above example, "whoever" is an indefinite relative pronoun. The protasis consists of "whoever has a sword and shield"; the apodosis, of "should help protect the wall".
But what about relative adjectives? Can a relative adjective describing the subject (or object) of a clause also give that clause conditional force?
Take whichever swords are at at hand; we shall need whichever arms you may find.
Are there conditions in the above example?
I ask because, as far as I know, what qualifies as a condition often requires certain particles or moods. It would thus affect the way I compose the above example in Greek.
I appreciate any feedback.
