Done up or clad eccentrically out East (5)
I believe the answer is:
laced
'done up' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I can't see?
'clad eccentrically out east' is the wordplay.
'eccentrically' is an anagram indicator.
'out' means one lot of letters goes inside another.
'east' becomes 'E' (synonyms).
'clad' anagrammed gives 'lacd'.
'lacd' placed around 'e' is 'LACED'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for laced that I've seen before include "reprimanded" , "Oxford will always be" , "Spiked - shoes are this" , "Drinks may be" , "with extra spirit" .)
