Selection of items arranged by caddy, might you say? (3,3)
I believe the answer is:
tea set
'selection of items' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'arranged by caddy might you say?' is the wordplay.
I cannot quite understand how this works, but
'arranged' could be 'set' (similar in meaning) and 'set' is found in the answer.
'caddy' could be 'tea' (synonyms) and 'tea' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tea set that I've seen before include "facility for refreshment" , "hot drink service" , "tableware" , "Crockery service" , "Set of crockery for serving light meal" .)
