First lady welcomes Guardian leaders insulating senators from convert (10)
I believe the answer is:
evangelise
'convert' is the definition.
Both the definition and answer are verbs in their base form.
Perhaps you can see an association between them that I can't see?
'first lady welcomes guardian leaders insulating senators' is the wordplay.
'first lady' becomes 'eve' (I've seen this before).
'welcomes' indicates putting letters inside (in sense of 'invites in').
'guardian' becomes 'angel' (I've seen this before**).
'leaders' says to take the initial letters.
The first letters of 'insulating senators' is 'is'.
'angel'+'is'='angelis'
'eve' going around 'angelis' is 'EVANGELISE'.
'from' acts as a link.
Can you help me to learn more?
