Go on a pub crawl, heading off with Foster, evoking strong emotions? (6)
I believe the answer is:
arouse
'go on' is the definition.
The definition and answer 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?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for arouse that I've seen before include "Cause to become awake" , "Excite, awaken" , "Energise" , "Evoke (a feeling)" , "Excite; wake from sleep" .)
