Main Entry: thresh*old 
Pronunciation: 'thresh-"hOld, 'thre-"shOld
Function: noun
Etymology: Middle English thresshold, from Old English threscwald; akin

Date: before 12th century
1 : the plank, stone, or piece of timber that lies under a door : SILL

I use "threshold" to indicate the sill for doors.  That makes it
completely distinct from window sills, and leaves the "saddle" to
describe the metal or wood thingy that sits under the door and is a
place for weatherstripping.  Think "straddle" in using saddle to cover a
vulnerable joint where the exterior threshold abuts the interior
flooring.
