Disgruntled Russian leader enters without clothes (6)
I believe the answer is:
narked
'disgruntled' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can sometimes define each other.
'russian leader enters without clothes' is the wordplay.
'leader' suggests taking the first letters.
'enters' means one lot of letters goes inside another.
'without clothes' becomes 'naked' (I've seen this in another clue).
The initial letter of 'russian' is 'r'.
'r' put inside 'naked' is 'NARKED'.
Can you help me to learn more?
(Other definitions for narked that I've seen before include "'Vexed, riled (6)'" , "Angry" , "Cross" , "Annoyed (informal)" , "Annoyed - upset - irritated" .)
