Characters in this word

Two or more meaningful parts placed together so that their meanings combine into a new one.

This origin belongs to the traditional form 開; 开 is its simplified writing.

  • 門門méndoor
  • 一一yīlatch and/or wooden pole that shuts a door
  • 廾廾gǒnga pair of hands

The traditional form 開 shows 廾, a pair of hands, and 一, a latch or pole, inside 門, a door: hands opening a latched door. The simplified 开 is a shorthand form, so its parts are not the original pieces.
