Kid almost gets yob to relax (5,3)
I believe the answer is:
chill out
'relax' is the definition.
(I've seen this before)
'kid almost gets yob' is the wordplay.
'kid' becomes 'child' (synonyms).
'almost' means to remove the last letter (most of the word but not all of it).
'gets yob' becomes 'lout' (I am not sure about this - if you are sure you should believe this answer much more).
'child' with its final letter removed is 'chil'.
'chil'+'lout'='CHILL OUT'
'to' is the link.
Can you help me to learn more?
(Other definitions for chill out that I've seen before include "Calm down, relax" , "Relax (inf.)" , "Relax (informal)" , "rest" , "Relax after energetic spell" .)
