This verb is evidently derived from the family of Latin words that includes lector ('reader') and lectare ('to read'). It does not occur outside lexicography, specifically in the Suda here and at lambda 403 (a different form of the same verb) and lambda 435. The Suda's source, according to Adler, is the unedited Lexicon codicis Barocciani 50.
Here, as in lambda 403 , lambda 435 and epsilon 829, a word of Greek orthography and morphology derived from Latin is ascribed to the language used "among Romans." See also delta 479 and, with less radical departures from the original Latin, delta 401, epsilon 1648, epsilon 1780, epsilon 3159, kappa 471 and lambda 221.
