The term 'user-begun' is a compound word formed from 'user' and 'begun'. 'User' originates from the Latin word 'uti', meaning 'to use', and 'begun' is the past participle of 'begin', which comes from the Old English 'beginnan'.

'User' evolved from the Latin 'uti' through Old French 'us', and 'begun' evolved from Old English 'beginnan'.

The term 'user-begun' has consistently meant 'initiated by the user' since its inception.
