Take lift up, saving time with children (5)
I believe the answer is:
filch
'take lift' is the definition.
'filch' can be an answer for 'lift' (thesaurus). I'm unsure of the 'take' bit.
'up saving time with children' is the wordplay.
'up saving time' becomes 'fil' (I am not sure about this - if you are sure you should believe this answer much more).
'with' says to put letters next to each other.
'children' becomes 'ch' (genealogical abbreviation).
'fil'+'ch'='FILCH'
Can you help me to learn more?
(Other definitions for filch that I've seen before include "Nick" , "Pilfer" , "Pinch, steal" , "Make off with what belongs to others" , "Rob" .)
