Welsh: y clafr

Status B
Subject: Agriculture
Part of speech: Noun, Masculine, Singular
Definition: Clefyd ar ddefaid, neu weithiau wartheg, a achosir gan y gwiddonyn Psoroptes ovis.
Notes: Os oes angen bod yn benodol yngylch y rhywogaeth yr effeithir arni gan y clefyd, gellir defnyddio 'clafr y defaid' neu 'clafr y gwartheg'. Gan amlaf bydd y testun Saesneg yn defnyddio 'sheep scab' a 'cattle scab' mewn achosion o'r fath, ond sylwer hefyd ei bod yn gyffredin defnyddio 'y clafr' ar ei ben ei hun yn Gymraeg am 'sheep scab' am fod y clefyd yn llawer mwy cyffredin ar ddefaid nag ar wartheg.
