Proof (verb)
From Hull AWE
The verb 'to proof' is mostly used nowadays in the sense of proof-read. It is a less formal word, and academic writers are advised to prefer the longer expression.
One other meaning is current, and will be of use to materials scientists, chemists and such technological and scientific fields. This is as a verb meaning 'to make something proof (in its adjectival sense) against some threat. One can for example proof a fabric or garment against rain, or a proof a building against vermin; a computer may be proofed against heat, or cold, or weather.
In American English, proofing is the normal spelling for what English bakers call proving dough: allowing the yeast to work and the mixture to rise.
