One nursed by tireless flying doctor? (9)
I believe the answer is:
sterilise
'doctor?' is the definition.
Both the answer and definition are verbs in their base form.
Maybe they are linked in a way I don't understand?
'one nursed by tireless flying' is the wordplay.
'one' becomes 'i' (Roman numeral).
'nursed by' is an insertion indicator.
'flying' indicates an anagram (letters fly around into new positions).
'tireless' anagrammed gives 'sterilse'.
'i' inserted into 'sterilse' is 'STERILISE'.
Can you help me to learn more?
(Other definitions for sterilise that I've seen before include "Disinfect" , "Listerise (anag)" , "Make free from micro-organisms, like surgeon's knife" , "Make free from bacteria" , "Free from germs" .)
