irregular -ru verb (-ri ending), intransitive verb
Archaic honorific verb equivalent to いらっしゃる or おられる in classical Japanese. Not used in modern speech; found only in historical texts.

In an old document it is written 'here he is (honorific).'
Derived from classical honorific verb います (to be, to go, to come) + archaic suffix がり. The exact historical derivation is uncertain.
