Point to angle being formed, as protractors do? (8)
I believe the answer is:
elongate
'protractors do?' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how they can define each other.
'point to angle being formed' is the wordplay.
'point' becomes 'E' (compass point).
'being formed' indicates an anagram.
'to'+'angle'='toangle'
'toangle' anagrammed gives 'longate'.
'e'+'longate'='ELONGATE'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for elongate that I've seen before include "Widen" , "Drag out" , "Gone late oddly to extend" , "Make longer" , "grow further" .)
