Carpet & rugs terminology
This sounds like a school class - but this is the one you don't want to miss. An educated buying decision translates into a buying success, and that is your goal. Certainly, understanding carpet and rug terminology is something you need for enjoyable, successful shopping. And it is not as simple as it may seem at first.
Criteria for dividing rugs into certain groups are fairly arbitrary, and so is term interpretation. More often than not, area rug is a mixed bag of attributes relating to different color/pattern styles, construction types, materials, and so on. Going from one retailer to another, you can expect a bit of puzzle every now and then - where does the rug you're interested in actually belong to?
The very definition of a rug vs. carpet is fairly lose. In general, area rug is larger than a rug and neither, unlike carpet, covers the entire floor. Since carpets need to fit variable floor shapes, their pattern/theme content is much more limited. Good side of it is that it saves carpets from fairly confusing design-related terminology of area rugs. That leaves only construction method and materials to focus on.
Rug/carpet construction is a complex technique of putting it together, from securing the yarn, to dyeing and chemical treatments. Usually, it is a particular technic of structuring/securing the yarn that determines construction type. According to it, most rugs and carpets come as tufted or woven. Within each of these two basic construction types, there are more or less numerous variations in particular techniques used.
Things get more complicated when it comes to area rug design, which is based on its color/pattern attributes. Multiple interpretations possible are potentially confusing in trying to figure out what some of the basic rug properties are. For instance, rug attributes like "Oriental", "Persian" or "European" most often have nothing to do with where the rug comes from, or how it's been made. Rather, it is an attempt to classify it according to its dominant pattern characteristic. Or, plainly, according to what it looks like.
Likewise, "Traditional" area rugs should feature some traditional pattern form, although it may be - and most often will be - machine-made. And vice versa, "Contemporary", or "Modern" area rugs may be very traditionally hand-made.
For instance, kilims were originally small hand-made flat-weave wool rugs with traditional tribal motifs. Nowadays, they can as well come as synthetic machine-tufted rugs of any size. There are many similar examples and, realistically, most of this kind of confusion with area rugs can't be avoided.
If the retailer can't figure out whether a rug is traditional or contemporary, it will likely be tossed into "Transitional" category.
In general, regardless of what a rug is called like, chances are, it is based primarily on rug's appearance, with other important aspects, such as construction type, or origin, varying widely. This gives one more reason to go beyond the formal rug attribute and focus on its actual physical properties: construction type - pile form, dyeing method, applied treatments - and materials it is made of.

Construction - Simply put, rug or carpet construction is a particular way of putting it together. Whether produced by hand, or by machine, they are made in a certain way. This includes all that is done to come up with a finished product: from tufting or weaving the yarn to dyeing and applying chemical or other treatments...
Materials - Nearly all of materials used for rug and carpet construction are in their face-fiber and backing. It is usually the face-fiber material that gets most of attention and consideration. This is because the rug/carpet fiber forming its face is most exposed, both, visually and physically. Hence it is the main determinant of appearance quality and retention...
Environmental effect - Most materials, natural or synthetic, have some environmental impact, and those used for carpets and rugs are no exception. Health hazard comes mainly from rug and carpet being outgassing potentially toxic fumes, as well as from rug and carpet mold (mildew) infestation...
Label and warranty - Rug/carpet label and its warranty can give important information and indications in regard to its quality level. Getting familiar with their contents is time well spent. Here's what you should look for...
Area rug size and shape - In somewhat different ways, area rug size and shape have both, functional and aesthetic aspect. At first, one would say that area rug's size is pretty much determined by dimensions of the space it is intended to. In reality, the decision on how large area rug will be, and whether it is to be square, round or of some other shape, should come after careful consideration of not only room's size and geometry, but also typical traffic patterns, form and arrangement of other objects and decor elements present, as well as the intended use of the room, or space...
Colors and Patterns - Color of your rug, or carpet, creates certain visual effect, emotion, and an atmosphere. Individual perceptions vary, but most of us will be affected similarly. Here's a brief overview of what are out typical responses to colors and patterns. It may help you decide what rug color and pattern type is best for your room...
Design style - Possible variations in the visual characteristics of the rug/carpet face - its design - are literally countless. They come from visual rug/carpet attributes created by both, fiber coloration, and its dimensional appearance. Luckily, all this immense variety is being channeled, fairly efficiently, into a few main classifications...
Carpet and rug buying checklist - The two main aspects of every rug or carpet are (1) its aesthetics and (2) practicality. Once you find the one that has the right looks, the next step is to check out how appropriate are its materials and construction type to its intended use. In other words, what is its quality level. The following checklist will help you figure that out...
