κατά

• κάδ (kád) – Epic, before δέ (dé)
• κατ᾽ (kat᾽) – apocope before a vowel with smooth breathing
• καθ᾽ (kath᾽) – apocope before a vowel with rough breathing

Perhaps from Proto-Indo-European *ḱm̥-teh₂, from *ḱóm.[1] Cognate with Hittite 𒅗𒀜𒋫 (katta, “down from, at, with, under”) and perhaps Old Welsh cant (“with”).
