速い（はやい） vs. 早い（はやい） – Fast vs. Early in Japanese
If you've ever studied Japanese or lived in Japan, you've probably encountered the word "はやい" (hayai). Interestingly, this term can be written with two different kanji: 速い and 早い. Both are pronounced the same way but carry distinct meanings.
In this article, we'll delve into the nuances of each term, explore their usage, and provide examples to help you use them correctly.
Understanding 早い (Hayai) – Early
The kanji 早い is used to express earliness or promptness in terms of time. It indicates that something occurs before the expected or usual time.

Use 早い when discussing events or actions that happen sooner than anticipated.
Understanding 速い (Hayai) – Fast
The kanji 速い conveys speed or quickness in movement or action. It's used when describing how fast something moves or how quickly an action is performed.
Examples:
車が速い (kuruma ga hayai) – the car is fast
速く走る (hayaku hashiru) – to run fast
反応が速い (hannō ga hayai) – the reaction is quick
Use 速い when referring to the speed of objects, actions, or responses.

While both 早い and 速い are pronounced "hayai," their meanings differ significantly:
早い: Relates to time; something occurring before the expected time.

Understanding the context is key to choosing the correct kanji.
