From Middle English stiff, stiffe, stif, from Old English stīf, from Proto-West Germanic stīf, from Proto-Germanic stīfaz, from Proto-Indo-European *steypós. See also West Frisian stiif, Dutch stijf, Norwegian Bokmål stiv, German steif; also Latin stīpes, stīpō, from which English stevedore. The expected Modern English form would be /staɪf/; /stɪf/ is probably originally from compounds such as stiffly, where the vowel was shortened before a consonant cluster.
