頻繁

1. Origins, structure, and basic meaning

• Structure: 頻繁 (ひんぱん) combines repeated frequency 頻 and abundance 繁 to mean frequent or often.
• Basic usage: It describes many cars passing and a machine stopping repeatedly.

2. Common pitfalls and similar expressions

• Frequency rather than intensity
  • 頻繁に says an event occurs often; it does not state that each occurrence is especially strong or long.
