Etymology
The word is a modern English compound formed by combining three distinct morphemes. The first, "water", traces its lineage directly from the Proto-Indo-European term for the essential liquid. The second, "proof", has a journey from Latin concepts of testing and proving, evolving in English to denote resistance, as in something that has been tested against a force. The suffix "-ing" is a native English element that nominalizes the adjective "waterproof". Thus, the literal construction "water-resistant-making" logically yields the modern abstract meanings of either the process of applying such resistance or the material that provides it.
