Travel in France - US soldier getting cold is hypersensitive (8)
I believe the answer is:
allergic
'hypersensitive' is the definition.
('allergic' can be a synonym of 'hypersensitive')
'travel in france us soldier getting cold' is the wordplay.
'travel in france' becomes 'aller' (I can't explain this - if you can you should believe this answer much more).
'us soldier' becomes 'gi' (I've seen this in other clues).
'getting' says to put letters next to each other.
'cold' becomes 'c' (eg on taps).
'aller'+'gi'+'c'='ALLERGIC'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for allergic that I've seen before include "Medically sensitive to" , "Hypersensitive (to certain substances)" , "Responding badly (to something)" , "Reacting (med.)" , "Having unfavourable reaction to foods or plants" .)
