когда

Etymology
, from which the following words also were derived: 🇨🇬, 🇨🇬, 🇨🇬,, 🇨🇬 / , 🇨🇬, 🇨🇬, 🇨🇬. Originally the word was probably *koda; compare 🇨🇬, 🇨🇬, Old Indic and 🇨🇬, Avestan kadā. From *koda came *kъdа, possibly under the influence of *kъdе, kъtо. On the other hand, one may perceive in the old instrumental singular *godō of the word  (the old meaning of which was “time, period”) with the interrogative particle ко-, making a genitive singular form *kogo goda (which time?). Thus the -гда ending may have derived from the genitive of.
