Has second thoughts about (4)

Ross

I believe the answer is:

rues

'has second thoughts about' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for rues that I've seen before include "Bemoans" , "Is sorry for - plants" , "Regrets, to be sure" .)

I've seen this clue in The Wall Street Journal, the L.A. Times Daily, The Washington Post and the Universal.
