Instances of most trouble with soldiers (7)
I believe the answer is:
moments
'instances' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Perhaps you can see a link between them that I can't see?
'most trouble with soldiers' is the wordplay.
'trouble' indicates an anagram.
'with' indicates putting letters inside.
'soldiers' becomes 'men' (men can mean a group of soldiers).
'most' is an anagram of 'mots'.
'mots' going around 'men' is 'MOMENTS'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for moments that I've seen before include "Short periods" , "Very brief periods of time" , "Points in time" .)
