Compositional etymology. This etymology is clearly derived from the etymology provided for λακάνη "dish", which is the koine form matching Attic λεκάνη. The etymology of the latter (see λεκάνη / λα- + χαίνω) could account for the koine variant, but not for the Attic form. Therefore a different etymology was designed by changing the first member and keeping the second member unchanged. There are several parallel cases in which two different dialectal forms of one and the same word are assumed to have different etymologies (see οὐρανός / ὠρεῖν, ἄρσην / ἔρδω). The alternative solution, favored by some grammarians, was to assume that one form was derived from the other through a formal change (pathos) and to assume only one etymon (see τάγηνον / τήκω, ἑστία / ἕζομαι)
