Japanese Learning: Expression to say how long an action takes

Look at the following sentence which we learned recently.

1. Ichi nichi ni San kai Gohan o Tabemasu. (I eat meals three times a day.)

The word “Ichi nichi” with particle “-ni” works as a reference time when talking about frequency.

However, today’s expression doesn’t have the particle “-ni” for a word of time period. It is because;

– Time period in the sentence is not a reference time to talk about frequency.

– The purpose is to talk about the time period itself.

– Even without the particle “-ni”, the word of time period can work as an adverbial.

Look at the following conversation and try to remember it;

A : Daigaku de Donokurai Nihongo o Benkyoushimashitaka.

 (How long did you study Japanese in the university?)

B : Daigaku de Yo nen Nihongo o Benkyoushimashita.

 (I studied Japanese four years in the university.)
