Bottom 6 strokes — graphically
而 (which historically depicted a beard or whiskers), but in
耑 these strokes show the spreading roots beneath the soil line. The full character is one continuous picture: sprout above (
山-shape), roots below (
而-shape).
耑 is the original graph behind
端 (extremity) and
喘 (panting); the 'tip / extremity' sense lives on in those daughter chars.
