Ring, and yearn to express a view (5)
I believe the answer is:
opine
'express a view' is the definition.
(I've seen this before)
'ring and yearn' is the wordplay.
'ring' becomes 'o'.
'and' means one lot of letters go next to another.
'yearn' becomes 'pine' ('pine' can be a synonym of 'yearn').
'o'+'pine'='OPINE'
'to' is the link.
(Other definitions for opine that I've seen before include "Hold forth" , "judge" , "Express one's view" , "Express a point of view" , "Proffer a view" .)
