neigh; whinny
The sound a horse makes; 'bray' is technically for donkeys, but may appear in some translations.
The neigh of a horse could be heard from afar.
Kanji form is uncommon; learners should use the kana spelling.
Derived from the verb いななく (to neigh). The exact origin of いななく is uncertain, but it is an old mimetic word for the sound a horse makes.
