Old English cnawan (class VII strong verb; past tense cneow, past participle cnawen), "to know, perceive; acknowledge, declare," from Proto-Germanic *knew- (cf. Old High German bi-chnaan, ir-chnaan "to know"), from PIE root *gno- "to know" (cf. Old Persian xšnasatiy "he shall know;" Old Church Slavonic znati, Russian znat "to know;" Latin gnoscere; Greek *gno-, as in gignoskein; Sanskrit jna- "know"). Once widespread in Germanic, this form is now retained only in English, where however it has widespread application, covering meanings that require two or more verbs in other languages (e.g. German wissen, kennen, erkennen and in part können; French connaître, savoir; Latin novisse, cognoscere; Old Church Slavonic znaja, vemi). The Anglo-Saxons used two distinct words for this, witan (see wit) and cnawan.
