I believe the answer is:

bounded

I'm a little stuck... Click here to teach me more about this clue!

'delineated' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?

Can you help me to learn more?

(Other definitions for bounded that I've seen before include "Finite" , "Limited and leaped" , "Confined" .)

I've seen this clue in The Irish News.
