'regularly-managed' originates from English, formed by the adverb 'regularly' and the past-participle adjective 'managed'. 'Regularly' ultimately comes from Latin 'regularis' (from 'regula' meaning 'rule'), and 'managed' comes from Italian 'maneggiare' via Old French (from Latin root 'manus' meaning 'hand').

'regularly' developed from Latin 'regularis' → (via Old French/Latin influence) Middle English 'regular' → English adverb 'regularly'; 'managed' derives from Italian 'maneggiare' → Old French 'manegier'/'maneger' → Middle English 'manage' with past participle 'managed'.

Initially, the components meant 'according to a rule' ('regularly') and 'to handle by hand' ('manage'). Over time these evolved so that 'regularly' denotes 'at fixed intervals or according to a schedule' and 'manage' came to mean 'control, administer, or maintain,' giving the modern sense 'kept under scheduled control or maintenance.'
