'meticulously-directed' is a modern compound formed from the adverb 'meticulously' (the adjective 'meticulous' + the adverbial suffix '-ly') and the past-participle adjective 'directed' (from 'direct'). 'Meticulous' ultimately comes via Latin and French routes; 'direct' comes from Latin.

'Meticulous' comes from Latin 'meticulosus' (meaning 'fearful'), through Late Latin and Old French into English as 'meticulous' in the 16th century; its sense shifted toward 'showing careful attention' in Modern English. 'Direct' derives from Latin 'dirigere' (to guide, set straight) → Late Latin 'directus' → Old French/Medieval Latin forms → Middle English 'direct', and its past participle 'directed' was used to mean 'guided' or 'ordered'. The compound 'meticulously-directed' is a descriptive combination formed in modern English to mean 'directed with meticulous care'.

Originally, 'meticulous' had a nuance of 'fearful' or 'timid' (from Latin), but its meaning shifted to 'extremely careful about details'; 'direct/ directed' originally meant 'to guide or set straight' and has retained the core sense of guiding; combined, the compound now means 'guided or controlled with painstaking care'.
