How do you spell Became in Japanese?

Answer 1

It depends on how you are using "becoming" but the simplest answer is Narimasu. Naru is the dictionary form of the verb. Narucoto is the gerund form. The weather is becoming cold" "samukuni narimasu"

Answer 2

'Became' may be either なった (natta) or なりました (narimashita) in Japanese. Both words come from the verbなる (naru), which means become. However, there is a difference in formality between the two.なった (natta) is casual andなりました (narimashita) is formal or polite.

Example:彼は有名になった (kare wa yuumei ni natta) - "He became famous."
