Etymology: "Rainproofing" is the gerund of "rainproof", so it names the act of making something impervious to rain. The adjective is a plain compound: "rain" joined to "proof," which in this sense means "resistant to" or "able to withstand," as in "fireproof" or "soundproof." The pattern dates from the early modern period, when English speakers built many such adjectives on the same model. The word "rain" has an ancient lineage. It comes from Old English "regn," which goes back through Proto-Germanic "regnąz" to a much older Indo-European root. The sound has shifted over the centuries, from the Old English "reġn" through Middle English "reyn" to the modern spelling, but the meaning has stayed remarkably steady for well over a thousand years.

Synonyms: waterproofing, damp-proofing, moisture-proofing, weatherproofing, sealant
