Unfortunately sent to small homes (5)
I believe the answer is:
nests
'homes' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'unfortunately sent to small' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'to small' becomes 's' (abbreviation - e.g. clothes size).
'sent' anagrammed gives 'nest'.
'nest'+'s'='NESTS'
Can you help me to learn more?
(Other definitions for nests that I've seen before include "Structures for egg-laying" , "Places to rear the young?" , "Tables made to fit closely together" , "Eyries" , "Cosy secluded retreats" .)
