What does detailed mean?
Detailed is an adjective describing something that includes or attends to many particulars: a detailed map shows every lane and footpath, a detailed report covers every line item, and a detailed explanation leaves no question unanswered. It carries connotations of care, precision, and thoroughness, and is generally positive when applied to work or analysis, though it can occasionally imply excessive length or pedantry. The word derives from the verb 'detail', which came through French from a root meaning 'to cut', so a detailed account is figuratively one that has been cut apart into its component pieces. English also retains the verb sense, especially in military and official language, where soldiers are 'detailed' for specific duties. In modern usage, 'detailed' is indispensable in professional writing, journalism, science, and everyday speech wherever accuracy and completeness matter.
Including or characterized by many details; thorough, precise, and itemized.
"The architect prepared detailed drawings before construction began."
Most often used attributively before a noun, but also common predicatively with verbs like 'be', 'give', and 'provide'.
Past tense and past participle of 'detail': to describe something fully and item by item, or to assign someone to a specific task.
"The manual detailed every step of the installation process."
The task-assignment sense survives chiefly in military and police contexts.
At its root, being 'detailed' literally means being cut into pieces — the word comes from French tailler, 'to cut', the same blade that gave us 'tailor'.

Etymology of detailed
Detailed is the participial adjective of the verb 'detail', which entered English in the early 17th century from French 'détailler', formed from 'de-' plus 'tailler' ('to cut'), ultimately from Latin 'talea' ('a cutting or twig'). The original sense was thus 'to cut into pieces', which evolved into 'to relate minutely' by cutting a subject down into its individual items. The same Latin-French cutting root produced English cognates such as 'tailor', 'retail', 'entail', and 'tally'.
