Unusually dry around central Greece - piping required (5)
I believe the answer is:
reedy
'piping required' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives occasionally mean the same thing.
'unusually dry around central greece' is the wordplay.
'unusually' indicates anagramming the letters.
'around' means one lot of letters goes inside another.
'central' indicates the central letters.
The centre of 'greece' is 'ee'.
'dry' with letters rearranged gives 'rdy'.
'rdy' enclosing 'ee' is 'REEDY'.
Can you help me to learn more?
(Other definitions for reedy that I've seen before include "Like some pipes" , "Thin and piping" , "Like some of the wind" , "Long and thin" , "Of voice, having thin high tone" .)
