'arts supporter?' is the definition.
'easel' can be an answer for 'supporter?'. I'm not certain of the 'arts' bit.

'eel as wriggly' is the wordplay.
'wriggly' indicates an anagram (I've seen this in other clues).
'eel'+'as'='eelas'
'eelas' anagrammed gives 'EASEL'.

Can you help me to learn more?

(Other definitions for easel that I've seen before include "Tripod supporting a canvas" , "Blackboard-frame" , "Support for artist's canvas" , "Picture frame" , "Three-legged supporting frame" .)
