## Hindi
### Etymology

Inherited from Old Hindi काहू (kāhū), काहु (kāhu), from Sauraseni Prakrit [Term?], from Sanskrit कक्षे (kákṣe, “in the armpit”), locative singular of कक्ष (kákṣa, “armpit”), from Proto-Indo-Aryan *káṭṣas, from Proto-Indo-Iranian *káćšas, from Proto-Indo-European *kóḱsos (“joint”). Compare Deccani کو (kū), Braj कौ (kau), Bengali -কে (-ke), Assamese -ক (-k).
The semantic development of the terms was in the armpit > at the side > towards > to. Deccani (and other Southern dialects of Hindustani) had a parallel development which also includes a locative sense.

#### Usage notes

When used to mark the accusative, it indicates saliency and definiteness of the object being marked. It is almost always used with human animate nouns.
को marks the dative. It can be used as a postfix similar to -wards (e.g. ऊपर को (ūpar ko, “upwards”); आगे को (āge ko, “afterwards”)). The dative is always preferred to be marked over the accusative sense.
It is suffixed to oblique forms of pronouns as well, e.g. the dative of मैं (ma͠i, “I”) is मुझको (mujhko).
