Come to a similar conclusion (5)
I believe the answer is:
rhyme
This might be a double definition.
'come' is the first definition.
Although both the answer and definition are verbs in their base form, I cannot see how one could define the other.
'similar conclusion' is the second definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'to a' is the link.
Can you help me to learn more?
(Other definitions for rhyme that I've seen before include "Correspond in sound" , "often quoted with reason" , "Be like 'cat' and 'mat'" , "'Moon' and 'June' do" , "Have identical terminal sounds" .)
