'honestly-managed' originates from Modern English, specifically the adverb 'honestly' (from 'honest') and the past participle 'managed' (from 'manage'), where 'honest' meant 'honorable' and 'manage' related to controlling or handling.

'honest' comes from Old French 'honeste' and from Latin 'honestus' (or 'honestas'), and 'manage' comes from Old French/Italian (Italian 'maneggiare') ultimately related to Latin 'manus' meaning 'hand'; these elements combined in Modern English as the compound adjective 'honestly-managed'.

Initially the roots signified 'honorable' (honest) and 'to handle or control (by hand)' (manage); over time they combined to describe something that is operated or administered with honesty — essentially unchanged in core sense but specialized as a compound describing management style.
