Proto-Celtic

Etymology

Disputed. Summarized from Irslinger (2002):

• Pedersen, implying *sɸlixstus, relates this to Ancient Greek πλίσσομαι (plíssomai) via a putative Proto-Indo-European *(s)pleygʰ-. Frisk, Mayrhofer, and Schrijver reject this connection.
• Foy, LEIA, Hamp (and also Matasović) go for a connection to Proto-Indo-European *stel- (“to spread”), via an extended *st(é)l-t-tus. This requires posing an isolated -t- extension to the root, which does not satisfy Irslinger.
• Irslinger, citing De Bernardo Stempel, prefers to derive this from a root *spelt-, avoiding the need for an aberrant root extension.
