Question: What does “weft” mean?

Answer:

Weft is the thread that goes across a piece of woven fabric.

In weaving, there are two main directions of threads:

          Warp threads
          ||||||||||||
          ||||||||||||
          ||||||||||||
Weft  ---> ============
Weft  ---> ============

Warp = the long threads stretched vertically on the loom (fixed, under tension)
Weft = the threads woven horizontally through the warp

A simple memory trick:

Warp = vertical (the “framework” that holds everything)
Weft = goes left-to-right (think “weft” → “weave across”)

Example:

A cotton shirt is made by weaving weft threads through warp threads.
The strength and structure of fabric often come from the warp; the weft gives texture, color patterns, and flexibility.

The phrase “warp and weft” is also used metaphorically:

“The warp and weft of society” = the fundamental structure and interconnections of society.

In computer graphics / GPU context, you might see “warp” again, but it is unrelated to textile weaving:

GPU warp = a group of usually 32 threads executing the same instruction together on NVIDIA GPUs.
The word was borrowed because a warp is a tightly connected bundle (like warp threads in fabric).
