Släkthistoria för Knivett
Knivett Vad efternamn betyder
perhaps as Reaney suggests a variant of Knight but this is far from proven. He attributes it to Norman difficulty in pronouncing the -h- in Old and Middle English cniht. This sound increasingly caused problems for native English speakers and was sometimes altered to [f] as early as the 13th century. This would account for Walter le Knift 1279 in Hundred Rolls (Oxon) but whether this is the source of Cnivet (11th century) and Knivet (13th and 14th centuries) with the intrusive -e- and voicing of [f] to [v] is quite uncertain. There is no evidence for knivet as a variant of knight in MED .perhaps from Middle English knivet knevet a diminutive form of knif ‘knife’ though the name is recorded much earlier than the word (15th-century in MED ).
