indeclinable (anurahoti is the locative/absolutive form; anuraho is the stem)
Analysis. anuraho (indeclinable adverb meaning 'secretly') + iti (quotative particle 'thus, so'), forming a postpositional phrase modifying verbs of action and speech to indicate covert or concealed manner.
Etymology. anu- ('along after, following the track of') + raho (from √ruh 'to hide, conceal'; Sanskrit rudhira 'blood', from the sense of flowing hidden), giving 'following along in concealment' — the prefix anu- suggests moving stealthily in the wake of something, reinforced by raho's root sense of secrecy and obstruction.
