The phrase 'meticulously-described' is formed from the adverb 'meticulously' (from 'meticulous') and the past participle 'described' (from 'describe'). 'Meticulous' comes from Latin 'meticulosus' meaning 'fearful' or 'timid', and 'describe' comes from Latin 'describere' meaning 'to write down'.

'Meticulous' entered English in the 19th century from Latin, and 'describe' has been in English since Middle English, from Latin. The compound 'meticulously-described' is a modern formation using these roots.

Initially, 'meticulous' meant 'fearful', but it evolved to mean 'showing great attention to detail'. 'Described' has always meant 'to give an account of'. Together, 'meticulously-described' now means 'described with great attention to detail'.
