Easily influenced president to remain in charge (7)
I believe the answer is:
plastic
'easily influenced' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives sometimes mean the same thing.
'president to remain in charge' is the wordplay.
'president' becomes 'p' (common abbreviation eg in VP).
'to remain' becomes 'last'.
'in charge' becomes 'ic' (abbreviation for 'in charge').
'p'+'last'+'ic'='PLASTIC'
Can you help me to learn more?
(Other definitions for plastic that I've seen before include "(Originally malleable) material" , "Generic name for certain synthetic materials" , "Fashionable - substitute for wood or metal" , "Pliant" , "Credit card - pliable" .)
