Doctor allowed to conceal operation tear (7)
I believe the answer is:
droplet
'tear' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'doctor allowed to conceal operation' is the wordplay.
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor').
'allowed' becomes 'let' (I've seen this before).
'to conceal' means one lot of letters goes inside another.
'operation' becomes 'op'.
'dr'+'let'='drlet'
'drlet' going around 'op' is 'DROPLET'.
Can you help me to learn more?
(Other definitions for droplet that I've seen before include "Small sphere of liquid" , "Small globule" , "Small amount of liquid" , "tiny amount of liquid" , "Small blob of liquid" .)
