Blurt out random hints, every so often (5)
I believe the answer is:
admit
'blurt' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'random hints every so often' is the wordplay.
'every so often' means one should take alternating letters.
'random'+'hints'='randomhints'
The alternating letters of 'randomhints' are 'ADMIT'.
'out' is the link.
Can you help me to learn more?
(Other definitions for admit that I've seen before include "Fess up" , "Confess; allow in" , "Allow entry" , "Provide student with place" , "Take on" .)
