Offer includes universal and large construct (5)
I believe the answer is:
build
'construct' is the definition.
(synonyms)
'offer includes universal and large' is the wordplay.
I cannot really see how this works, but
'universal' could be 'u' and 'u' is located in the answer.
'large' could be 'l' (eg in clothes sizes) and 'l' is found within the answer.
'offer' could be 'bid' (synonyms) and 'bid' is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for build that I've seen before include "Put up" , "Increase gradually" , "Construct" , "Create" , "Institute" .)
