Compound word
构词法gòucífǎ

Two parts of equal weight, alike or opposite in meaning, standing side by side.

约yuērestrict

约 means to restrict, and 束 means to bind, so the word means to keep something within limits.

Characters in this word

Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

This origin belongs to the traditional form 約; 约 is its simplified writing.

The sound has drifted apartThe sound part was a clue two thousand years ago — it often still helps, but not always.

The traditional form 約 uses 糸, a rope, for its meaning and 勺 for its sound; the simplified 约 is a later shorthand.
