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 頻; 频 is its simplified writing.

For 频, the traditional form 頻 came from an older form showing a person near water and meaning 'on the verge'; one part was later removed to mark the 'frequent' use.
