***** NOT A TEACHER *****

Hello,

Here are some ideas that I found on the Web:

  1. The expression “forewarned, forearmed” can be expanded to:

(a) To be forewarned is to be forearmed. (As Anglophile told us.)
(b) If one is forewarned, one is forearmed.
© He who is forewarned is forearmed.

  1. Almost everyone seems to agree that “forearmed” should be parsed as an ADJECTIVE.

  2. Some people seem to think that “forewarned” is also an adjective in that expression.

a. I think that they say the original expression in Latin consists of two participles that are ADJECTIVAL: “praemontius, praemunitus.”

  1. Some people seem to think that “forewarned” in that sentence has the force of a VERB.

***** MY OPINION *****

Who is right?

Of course, I do not know.

But I tend to think that “forewarned” is a verb:

Tom: You are very lucky. There was a big fight at school yesterday, but you were not there.

Mona: I was not lucky. I was forewarned.

Tom: Who forewarned you?

Mona: I was forewarned by George. He told me that his buddies were planning a big fight, so I left school early.

Tom: Oh, I see: Forewarned, forearmed.

Mona: Exactly.
