interior_design_mug-resized-600Every profession has it’s own special language and Interior Design, Architecture and Construction are no different.

Each week I will be giving you definitions for different letters of the alphabet and will continue through the alphabet until we are done with all of the letters.

Here are some definitions beginning with the letter “D”



A dado is a type of joint in woodworking where a groove is cut out for another piece of perpendicular wood to be inserted such as in drawer construction or in shelving.

As mentioned above it is also used to describe what is commonly known as wainscoting. (not wainscoating)



Damask weaving began in Damascus, Syria but today refers to either the flat satin weave where the fabric has the the opposite design on the back side of the fabric or it refers to the design which is often tone on tone.  It can be found in many different fabrics including silks, cotton and blends.


Delamination is not desirable.  It is a defect in the finish of a product that has been fused together and is now coming apart.  De-laminate as in Un-laminate!  This is not easy to fix because the laminating process is done commercially with high heat. Delaminating occurs where there is lamination that has been infiltrated by water, air or some other substance.  The culprit is often water infiltration.



Demilune tables are easy to spot because they are “half- circles”.  The back side is flat and goes against a wall or other flat surface. Demi mean “half” and “lune” mean moon in French.



Dentil molding is commonly used in traditional and classical architecture and furnishings.  It is comprised of a continuous rhythm of small blocks evenly spaced that are reminicent of teeth – therefore “dentil”.



A diffuser in Architectural and Contruction terms refers to the way air is directed by means of levers or slats.  Diffusers are used on HVAC (Heating, Ventilation and Air Conditioning) units to control the flow of air into and out of the system.



Although most walls are made of single stud framing, double stud framing is used to create a sound barrier and trap a void between the two suds which helps with insulation.  Obviously, is is also more structurally sound but will require custom trimming out at doors and windows  because it is not the standard size.




The French word “Duvet” refers to the outer covering of a down or synthetic comforter.  Duvet covers are popular because they can be laundered and don’t require a lot of fuss when making a bed.  They are not as long as a bedspread so they usually reaquire a bed skirt to hide the box springs.



You’ve probably heard the term “dovetail” but may not know exactly what it refers to.  These pictures show how drawers are finished with dovetail joints to make them strong.  Dovetails are composed of a mortise and tenon, which fit tightly together and do not loosen easily because of the flared shape of the “dovetail”.  The word comes from the shape of the tenon – a dove’s tail.


Dupioni silk has a specific look to it with visable slubs (soft nubs or twists in the yarn) showing randomly.  This occurs when the silk is woven because of the uneven thickness of the threads used to weave this fabric that happens when the yarn is spun.

Next week I will define terms beginning with the letter “E”.
