Sweetheart, search nursery for bees! (9)
I believe the answer is:
honeycomb
'nursery for bees' is the definition.
I can't tell whether this definition defines the answer.
'sweetheart search' is the wordplay.
'sweetheart' becomes 'honey' (I've seen this in another clue).
'search' becomes 'comb' (combing is a kind of searching).
'honey'+'comb'='HONEYCOMB'
Can you help me to learn more?
(Other definitions for honeycomb that I've seen before include "Bewildering maze" , "Hive storage structure" , "pattern of cells" , "Jewish festival of lights" , "pattern created by workers" .)
