’e is adept and can be avoided (9)

'avoided' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can sometimes mean the same thing.

''e is adept and can' is the wordplay.
'is adept' becomes 'capable' (I've seen this before).
'and' says to put letters next to each other (I've seen this in other clues).
'can' becomes 's' (I can't justify this - if you can you should believe this answer much more).
'capable' put after 's' is 'scapable'.
'e'+'scapable'='ESCAPABLE'

'be' is the link.
