Each son of Trump admits government is hypersensitive (8)
I believe the answer is:
allergic
'hypersensitive' is the definition.
(synonyms)
'each son of trump admits government' is the wordplay.
'each' becomes 'all' (similar in meaning).
'son of trump' becomes 'eric' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'admits' indicates putting letters inside (to admit is to allow in).
'government' becomes 'g' (abbreviation for government).
'eric' placed around 'g' is 'ergic'.
'all'+'ergic'='ALLERGIC'
'is' is the link.
Can you help me to learn more?
(Other definitions for allergic that I've seen before include "Having unfavourable reaction as to certain foods, pollen etc" , "acting defensively" , "Reacting (med.)" , "Having an adverse reaction (to something)" , "Hypersensitive (to a substance)" .)
