Proto-Basque: *siga-r̄
Meaning: itch mite (arthropod: Sarcoptes scabiei)
Bizkaian: ziger, (Gernika) zigar, (Ispaster, Markina) zier
Gipuzkoan: zigar
Lapurdian: zigar
Comments: Cf. Span. cigarra 'cicada' (Hualde 1995), which resembles Bsq zigar in form, though there is a vast physical difference between the large insect and the tiny arthropod. Cigarra is ostensibly from Lat. cicada or cicala, but the trilled /r̄/ could indicate some kind of influence from the Bsq word.
