Discourage day trip after Juliet drops out (5)

I believe the answer is:

daunt

'discourage' is the definition.
(I've seen this before)

I don't understand the remainder of the clue.

(Other definitions for daunt that I've seen before include "Make to feel intimidated" , "Discourage" , "Cause to feel intimidated" , "Dishearten" , "Make (someone) apprehensive" .)

I've seen this clue in The Times.
