Hi Cowboy

This may help

=====
A dado (US and Canada), housing (UK) or trench (Europe) is a slot or trench cut into the surface of a piece of machinable material, usually wood.
When viewed in cross-section, a dado has three sides.
A dado is cut across, or perpendicular to, the grain and is thus differentiated from a groove which is cut with, or parallel to, the grain.

A dado may be through, meaning that it passes all the way through the surface and its ends are open, or stopped, meaning that one or both of the ends finish before the dado meets the edge of the surface.

Dados are often used to fix shelves to a bookcase carcase.
Combined with a rebate (rabbet) on an adjoining piece, they are used to make the rebate and dado joint, sometimes used in case goods.

SURE ENOUGH --- there it was rebate= variation of rabbet
But -- whichever way you say it -- is a rebate/rabbet not a two-sided notch cut along the edge or face of a board?

I ask --because the post where I pulled this quote - the poster was referring to mounting drawer support frames into dovetails cut into rebates in the sides.

To me a three-sided groove cut in a board has always been a dado (or just a groove).

No -- I am not being a smart mouth - it's a genuine question.
Since I didn't realize until today that a rabbet could be a rebate -
-- I have to wonder now if my definition is too narrow -
if a rabbet/rebate can also be a dado???
