Loyalty, for example, in coalition (10)
I believe the answer is:
allegiance
'loyalty' is the definition.
(allegiance is a kind of loyalty)
'example in coalition' is the wordplay.
'example' becomes 'eg'.
'in' is an insertion indicator.
'coalition' becomes 'alliance' (alliance is a kind of coalition).
'eg' put into 'alliance' is 'ALLEGIANCE'.
'for' acts as a link.
(Other definitions for allegiance that I've seen before include "Loyalty (to a superior)" , "Loyalty to a group or cause" , "commitment to a cause" , "Fidelity" , "duty" .)
