What does delineated mean?
"Delineated" is the past tense and past participle of "delineate", a formal verb meaning to describe or depict something precisely, or to trace its exact outline or limits. When a plan, argument, or set of duties has been delineated, it has been laid out with enough detail that little room for ambiguity remains. The word carries connotations of precision and care, making it at home in legal contracts, academic papers, architectural drawings, and literary criticism — a reviewer might praise a novelist's sharply delineated characters, for instance. It derives from the Latin "delineare", literally "to sketch out by lines", combining "de-" with "linea" (line), so the word's core image of drawing lines around a shape survives even when it is used purely metaphorically. Writers choose it over plainer alternatives like "described" when they want to stress exactness and definition.
Past tense and past participle of "delineate": described or portrayed precisely, or traced the outline of.

Almost always appears in formal contexts such as legal, academic, or technical writing.
Clearly defined, outlined, or marked out.
"The essay presented a well-delineated thesis supported by careful evidence."
Typically used attributively with modifiers such as 'clearly', 'sharply', or 'finely'.
The 'line' hiding inside 'delineate' is no accident — the word literally means 'to draw lines around', which is why a sharply delineated character in a novel feels like a finished portrait rather than a vague sketch.

Etymology of delineated
"Delineated" comes from Latin "delineatus", the past participle of "delineare", meaning "to sketch or trace in outline", from "de-" plus "linea" (a line). The word entered English in the early 16th century, initially carrying the literal sense of drawing outlines before broadening to precise verbal description. It shares its root with words like "lineage", "linear", and "lineament", all ultimately descended from Latin "linea".
