There appears to be a great deal of remnant sound symbolism in the Yahgan lexicon. For example, many roots ending in -m encode as part of their senses the notion of a texturally softened positive curve (similar to -mp in such words as lump or hump in English), while an -l in similar position often shows up when the reference is to bloody core parts, often out from once safe confinement inside the body. Many roots with initial ch- refer to repeated, spiny extrusions, final -x to dry, hard-edged, or brittle parts, and so on.
