Drug supplier swans into entrance to Scotland Yard, I suspect (10)
I believe the answer is:
dispensary
'drug supplier' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'swans into entrance to scotland yard i suspect' is the wordplay.
'swans' becomes 'pens' (pen can mean a female swan).
'into' is an insertion indicator.
'entrance to' indicates taking the first letters.
'suspect' indicates an anagram (a suspicious or unusual spelling).
The first letter of 'scotland' is 's'.
's'+'yard'+'i'='syardi'
'syardi' is an anagram of 'disary'.
'pens' put into 'disary' is 'DISPENSARY'.
Can you help me to learn more?
(Other definitions for dispensary that I've seen before include "Drug dealer" , "source of drugs?" , "Place providing medicines" , "Pharmacy" , "Medical provider" .)
