Say loudly: "I'll pay!" (5)
I believe the answer is:
shout
'say' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for shout that I've seen before include "Noise" , "Utter a loud cry" , "Call loudly" , "(Statement) with opposite sense intended" , "Yell" .)
