Hold on to outside right to enhance skills (7)
I believe the answer is:
retrain
'hold' is the definition.
Both the answer and definition are verbs in their base form.
Maybe they are linked in a way I don't understand?
'on to outside right to enhance skills' is the wordplay.
'on' becomes 're' (regarding).
'to outside' is an insertion indicator (some letters go outside others).
'right' becomes 'r' (abbreviation).
'to enhance skills' becomes 'tain' (I am not sure about this - if you are sure you should believe this answer much more).
'r' placed inside 'tain' is 'train'.
're'+'train'='RETRAIN'
Can you help me to learn more?
(Other definitions for retrain that I've seen before include "Learn new skills" , "Study for new job" , "Teach (someone) new skills" , "Prepare for new job" , "Take a different course" .)
