What does cluey mean?
"Cluey" is an informal adjective used chiefly in Australia and New Zealand to describe someone who is knowledgeable, shrewd, or well-informed about a particular subject or situation. It derives from the noun "clue", in the sense of information that guides understanding, and carries a broadly approving connotation: to call someone cluey is to compliment their practical savvy or good judgment. The word typically appears in casual speech and journalism rather than formal writing, often in patterns such as "cluey about" or "cluey on" a given topic. A related and more widespread British expression is "clued-up", which shares the same underlying metaphor. For readers encountering it outside Australasia, context usually makes its meaning clear, but its regional flavour makes it a distinctive marker of Australian and New Zealand English.

Etymology of cluey
The word is formed by adding the adjectival suffix "-y" to "clue", a noun of uncertain origin first recorded in the late sixteenth century, possibly a variant of "clew" meaning a ball of thread — the thread of Ariadne from Greek myth being the classic guide through a labyrinth. "Cluey" emerged as a colloquial adjective in Australian and New Zealand English during the twentieth century, following the pattern of similar formations such as "corker-y" style adjectival coinages. Its closest relative is the British informal "clued-up", which developed from the phrasal verb "to clue up".
