🩹 BENG! You snap the elastic DAI-ly wrap around your wound
The stretchy sound 'beng' echoes the snap of elastic fabric being pulled taut, while 'dai' sounds like 'daily' — something you change daily on a healing wound. 绷 means to stretch tight, 带 means strip or band.
绷 — silk radical 纟 + 朋 (bēng phonetic)
A semantic-phonetic compound. The silk radical 纟 indicates the meaning, originally referring to binding or wrapping with cords or cloth. The component 朋 supplies the sound. From 'tie tightly' the meaning extended to 'stretch taut,' 'strain,' and colloquially 'to hold back' or 'put on a stiff face.'
带 — belt/sash 巾 at bottom + ornaments above
带 originally pictured a belt or sash with hanging ornaments or pendants tied at the waist; the bottom 巾 (cloth) reinforces the textile meaning. From the literal 'belt' it extended to 'carry, bring along' (as a belt holds things) and to 'zone/region' (a strip of land).
