Carried out prize for engineering degree (8)
I believe the answer is:
honoured
'carried out' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe you can see an association between them that I don't see?
'prize for engineering degree' is the wordplay.
'prize' becomes 'honour' (I've seen this before).
'for' says to put letters next to each other.
'engineering degree' becomes 'ed' (this might be a standard abbreviation I've not previously seen).
'honour'+'ed'='HONOURED'
Can you help me to learn more?
(Other definitions for honoured that I've seen before include "Greatly respected" , "given recognition" , "Bestowed accolades or awards" , "Conferred with laurels" , "Regarded with respect" .)
