Gerald or Henry (4)
I believe the answer is:
ford
'gerald or henry' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ford that I've seen before include "Shallow part of stream to cross" , "Shallow place for river crossing" , "Car - river crossing" , "River or stream crossing" , "38th US president, Gerald" .)
