Origin & Mnemonic:

At ease, comfortable, or convenient through change. Convenient (biàn); then / just; cheap or advantageous (pián). A person (亻) plus change (更): someone adjusting things to make life easier.

Common Usage & Traps

  • 便宜 (pián yi) — cheap; inexpensive
  • 方便 (fāng biàn) — convenient
  • 大便 (dà biàn) — feces; to defecate
  • 小便 (xiǎo biàn) — urine; to urinate
  • 很便宜 便宜

    便宜 already means 'cheap'; adding 很 is redundant and unnatural in most contexts.

  • 便 alone meaning cheap 便宜

    便 alone never means 'cheap'; the meaning 'cheap' only appears in the fixed word 便宜.

When should I use 便 instead of 就 to mean 'then'?

便 and 就 are often interchangeable, but 便 is more formal and common in writing.

Both 便 and 就 can mean 'then' or 'in that case', but 便 is slightly more formal and frequently used in written Chinese. In everyday speech, 就 is more natural. For HSK 1, focus on 就 for spoken contexts and recognize 便 in reading.

DimensionNaturalAvoid
Spoken我就去。我便去。 (too formal)
Written他便离开了。他就离开了。 (less formal)

Why is 便宜 pronounced piányi instead of biànyí?

便宜 is a special case where 便 is read pián, not biàn.

The character 便 has two readings: biàn (convenient, then) and pián (only in 便宜, meaning cheap). 便宜 is the only common word where 便 is read pián. Remember it as a fixed expression.

Meaning cheap便宜 (piányi)便谊 (wrong characters)
Meaning convenient方便 (fāngbiàn)方便 (fāngpián) (wrong pronunciation)
