Don't forget to carry inside and look after (4,2,4)
I believe the answer is:
bear in mind
'don't forget' is the definition.
I can't tell whether this defines the answer.
'carry inside and look after' is the wordplay.
'carry' becomes 'bear' (bear can mean to transport or carry).
'inside' becomes 'in' ().
'and' says to put letters next to each other.
'look after' becomes 'mind' (I've seen this before).
'bear'+'in'+'mind'='BEAR IN MIND'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for bear in mind that I've seen before include "Consider" , "what big game hunter may have" , "Take into consideration" , "Remember and take into account" .)
