Glossary of Plaid and Tartan Terms

A reference guide to the terminology used throughout this site and in the broader world of plaid, tartan, and woven textiles.
Ancient
A color palette for tartan that uses lighter, more muted tones meant to replicate the appearance of tartan dyed with traditional vegetable dyes. Compare with Modern and Weathered.
Buffalo Check
A bold check pattern of large, equal-sized blocks in two alternating colors, most classically red and black. See Buffalo Check.
Check
A pattern of squares formed by crossing horizontal and vertical stripes, usually in two or three colors. Generally simpler than a plaid or tartan. See Plaid vs. Tartan vs. Check.
Clan Tartan
A tartan pattern associated with a specific Scottish clan or family. The modern clan tartan system was largely formalized in the 19th century. See Clan Tartans Guide.
Colorfast
Describes a dye that does not bleed or fade when washed. Traditional madras uses dyes that are not fully colorfast.
Dress Tartan
A variation of a clan tartan that adds white to the sett, traditionally worn for formal occasions. Originally associated with women's wear in Highland dress.
Féileadh Beag
Scottish Gaelic for 'small plaid' — the modern kilt, evolved from the lower portion of the great belted plaid.
Féileadh Mòr
Scottish Gaelic for 'great plaid' — the large rectangular piece of tartan cloth worn as a full-body garment in traditional Highland dress. Precursor to the modern kilt.
Flannel
A soft fabric (cotton or wool) that has been brushed to raise a fuzzy nap. Not a pattern — flannel can be solid, plaid, or printed. See Flannel Fabric.
Gingham
A simple woven check pattern using two colors (usually white and one other), creating a three-tone effect. See Gingham Pattern.
Glen Plaid
A complex pattern combining small and large checks, originating from the Glenurquhart estate in Scotland. Also called Prince of Wales Check. See Glen Plaid.
Houndstooth
A broken check pattern with distinctive four-pointed tooth-shaped forms at each intersection, created by a specific twill weave arrangement. See Houndstooth Pattern.
Hunting Tartan
A version of a clan tartan using darker, more subdued colors designed for outdoor wear and concealment.
Madras
A brightly colored, lightweight cotton plaid from Chennai (formerly Madras), India. Traditionally uses vegetable dyes that bleed. See Madras Plaid.
Modern (color palette)
A tartan color palette using bright, fully saturated colors achieved with modern chemical dyes. The most common version sold commercially. Compare with Ancient and Weathered.
Nap
The raised, fuzzy surface of a brushed fabric like flannel. Created by mechanically brushing the woven fabric to pull fibers up from the surface.
Overcheck
An additional stripe or grid pattern layered over a base pattern. In glen plaid, a colored overcheck turns it into a Prince of Wales check.
Pivot Point
The point in a symmetrical tartan sett where the color sequence reverses direction, creating a mirror-image pattern.
Plaid
In North America, any pattern of crisscrossing horizontal and vertical stripes. In Scotland, a garment — a rectangular piece of tartan cloth worn over the shoulder or as a blanket. See Plaid vs. Tartan vs. Check.
Selvedge (Selvage)
The finished edge of a woven fabric that prevents unraveling. On tartan and plaid fabrics, the selvedge often shows the thread colors used in the weave.
Sett
The complete repeating unit of a tartan pattern — the sequence of colored threads that defines the design. See How Tartan Is Woven.
Tartan
A pattern defined by a specific sett (thread sequence) woven in a twill weave, with the same sett used in both warp and weft. See Tartan Pattern.
Tattersall
A check pattern of thin, evenly-spaced lines in two alternating colors on a light background. Named after Tattersall's horse market in London. See Tattersall Check.
Thread Count
The numerical specification of a tartan sett, listing each color and the number of threads in each stripe. Maintained by the Scottish Register of Tartans.
Tweed
A rough-textured, durable wool fabric traditionally woven in Scotland and Ireland. Often features check, herringbone, or plaid patterns.
Twill Weave
A weave structure where each thread passes over two or more threads and under one or more, creating diagonal lines on the fabric surface. Tartan uses a 2/2 twill.
Warp
The vertical threads on a loom, held under tension. In tartan, the warp and weft use the same sett sequence.
Weathered
A tartan color palette using muted, earthy tones that simulate the appearance of tartan that has been faded by exposure to the elements. Compare with Modern and Ancient.
Weft
The horizontal threads woven through the warp on a loom. In tartan, the weft follows the same sett as the warp.
Windowpane
A simple plaid pattern of thin, widely-spaced lines forming a grid on a solid background, resembling window panes. See Windowpane Plaid.
Worsted
A type of yarn and fabric made from long, combed wool fibers, producing a smooth, crisp textile. Used for suiting and fine garments.
