Spelt out end, shielded from harsh temperatures? (10)
I believe the answer is:
stipulated
'spelt out' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'end shielded from harsh temperatures?' is the wordplay.
I cannot really understand how this works, but
'end' could be 'tip' (tip is a kind of end) and 'tip' is found within the answer.
'from' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for stipulated that I've seen is " Required, specified".)
