Note 102: “One has to agree with Leslau (CDG 533) who believes that Arb. širš- ‘root’ (Dozy I 745) “does not give the impression of being an original Arabic root.” “
Arabic
šaršūr- - a small bird
(BK I 1214, Lane 1525, LA IV 403)
It is not clear whether the meaning of the last form refers to the singular or the plural: data from other dictionaries corraborate the former suggestion (Dozy I 754, Belot Arb.-Fr. 371).
