'chronicle-focused' is a compound formed from 'chronicle' and 'focused'. 'chronicle' ultimately originates from Greek via Latin, specifically the Greek word 'khronos' (χρόνος), where 'khronos' meant 'time'; 'focused' derives from Latin 'focus', where 'focus' originally meant 'hearth' and later 'center'.

'chronicle' came into English via Medieval Latin 'chronica' and Old French 'cronique' before becoming Middle English 'cronicle' and modern English 'chronicle'. 'focus' entered English from Latin 'focus' and developed the adjectival/past-participle form 'focused' in modern usage; the compound 'chronicle-focused' is a recent formation created by joining these elements in contemporary English.

Individually, 'chronicle' originally related to time or a record of events, and 'focus' related to a hearth or center; together in modern usage the compound means 'centered on recording events in chronological order.'
