Only when warp and weft interweave can you make cloth.
Tips
memory
The 纟 (silk) radical reveals the original meaning: the horizontal thread on a loom. Pair it with 经 (jīng, warp / longitude) — together 经纬 means both 'warp and weft' and 'longitude and latitude'.
usage
Common compounds: 纬度 (latitude), 北纬/南纬 (north/south latitude), 经纬 (warp and weft; also figurative for principles or affairs of state).
