Peg fully lifting a million tonnes? (8)
I believe the answer is:
margaret
'peg fully' is the definition.
The definition suggests a singular noun which matches the answer.
'lifting a million tonnes?' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
'million' could be 'a' (synonyms) and 'a' is found within the answer.
'tonnes?' could be 't' (abbreviation) and 't' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for margaret that I've seen before include "Scottish Queen/Saint" , "Thatcher, perhaps" , "Woman" , "Name of saintly Scottish queen" , "Girl's name" .)
