Proto-Celtic

Etymology

From Proto-Indo-European *péy-tu-s ~ *pi-téw-s (proterokinetic tu-stem) (whence Sanskrit पितु (pitú, “nutrition”), Avestan 𐬞𐬌𐬙𐬎 (pitu, “food”)), from *pey- (“food, nutrition”) +‎ *-tus.^[1] Cognate with Proto-Slavic *piťa, Lithuanian piẽtūs (“dinner”, pl.), Boeotian Greek πιτεύω (piteúō, “to irrigate, to water (cattle)”).

Noun

*ɸitu n^[2]

corn, grain

Reconstruction notes

This word may still have declined hysterokinetically in Proto-Celtic, with root ablaut: nom.sg. *ɸētu, gen.sg. *ɸitows. The former, strong, stem developed into Old Irish íath (“land”); the latter, weak, stem gave ith (“corn, grain”).^[3]
