Capable of a lack of sentiment, daughter’s planning mischief? (2,2,2,4)
I believe the answer is:
up to no good
'capable' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'lack of sentiment daughter's planning mischief?' is the wordplay.
I cannot quite see how this works, but
'sentiment' could be 'goo' (goo can mean sentimentality) and 'goo' is found in the answer.
'planning' could be 'upto' (I've seen this in another clue) and 'upto' is found within the answer.
'daughter' could be 'd' (genealogical abbreviation) and 'd' is found within the answer.
'lack of' could be 'no' (lack of money is no money) and 'no' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'of a' is the link.
Can you help me to learn more?
(Other definitions for up to no good that I've seen before include "Doing something wrong" , "Scheming to do wrong(2.2.2.4)" , "Misbehaving" , "Making mischief" , "Doing something mischievous" .)
