粘り
ねばり · nebari · JLPT N1 · noun
stickiness
🍯 粘る (nebaru, to stick) + り = the noun: stickiness, the quality of sticking
Same root as 粘り強い (nebari-zuyoi, persistent). Natto's 粘り is its stringy stickiness, and honey shows the viscosity sense.
粘 — rice 米 + occupy 占 (phonetic)
A semantic-phonetic compound: 米 (rice) gives the meaning, since sticky rice paste was a common adhesive, while 占 supplies the sound. The character originally referred to glutinous, sticky substances like rice paste, and later broadened to mean 'sticky' or 'to stick/adhere' in general.
