Shy about hugging US private into posturing? (5)
I believe the answer is:
yogic
'into posturing?' is the definition.
'shy about hugging us private' is the wordplay.
'shy' becomes 'coy' (I've seen this before).
'about' is a reversal indicator.
'hugging' means one lot of letters goes inside another.
'us private' becomes 'gi' (term for US soldier).
'coy' written backwards gives 'yoc'.
'yoc' placed around 'gi' is 'YOGIC'.
(Other definitions for yogic that I've seen before include "of meditation" , "-- flying is TM method" , "posturing?" , "Related to Hindu philosophy" , "Relating to a Hindu system of philosophy" .)
