Skill acquired in regular teaching (3)
I believe the answer is:
art
'skill' is the definition.
(thesaurus)
'in regular teaching' is the wordplay.
'in' indicates a hidden word.
'ART' is hidden in the letters of 'regular teaching'.
'acquired' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for art that I've seen before include "For example, Blakey's creative" , "Trickery" , "Works of creative imagination" , "Work such as paintings or sculptures" , "Expertise" .)
