Support child with limited help (7)
I believe the answer is:
chassis
'support' is the definition.
(I've seen this before)
'child with limited help' is the wordplay.
'child with' becomes 'ch' (I can't justify this - if you can you should believe this answer much more).
'limited' means to remove the last letter.
'help' becomes 'assist' (assisting is a kind of helping).
'assist' with its last letter removed is 'assis'.
'ch'+'assis'='CHASSIS'
Can you help me to learn more?
(Other definitions for chassis that I've seen before include "Vehicle structure" , "Car's body" , "Body framework" , "basic structure" , "Support" .)
