Worker evoking Arden era to some extent (8)
I believe the answer is:
'worker' is the definition.
(type of worker)
'evoking arden era to some extent' is the wordplay.
'to some extent' indicates a hidden word.
'GARDENER' is hidden within 'evoking arden era'.
(Other definitions for gardener that I've seen before include "He tends cultivated land around house" , "One may get food" , "Cultivator" , "Tender of plants" , "one working on plot?" .)
