'occasionally-carried' is a compound word formed from 'occasionally' and 'carried'. 'Occasionally' originates from Latin 'occasio', meaning 'a happening' and 'carried' is the past participle of 'carry', from Old French 'carier', meaning 'to transport'.

'Occasionally' evolved from Middle English 'occasional' and 'carried' from Old French 'carier', eventually forming the modern English compound 'occasionally-carried'.
