 I know.

 okay, I'll use imaginary examples for this...

 "ron  gyrouin edak!"
'ron' being the trigger, turning it from a nice, quiet question about cars,
to a matter of life or death (but still a question about cars).

or, maybe -

"gyrouin ron edak"
(I think)

as opposed to...

"ron'edak gyrouin"
in which the 'trigger' has merged with the word that it was
affecting...which is what I *had* thought was an initial consonant mutation
(becoming "son'edak" in some cases).
