Definition and meanings of “hiroi”

Let me start with the definition and meanings of “hiroi”.

• hiroi – 広い (ひろい) : an i-adjective meaning ‘wide’, ‘broad’, or ‘spacious’ in Japanese.

Japanese native speakers use this i-adjective to describe something large in width or something spacious. So, the usage is very similar to those of the English adjectives written above.

The definition and meanings are not that difficult, I think. Then, let me explain how to use this i-adjective through the example sentence below.

Example #1: how to say “spacious” in Japanese

Below are the new words used in the example sentence.

• kono – この : a determiner used before a noun which refers to something close to the speaker. In the example, this is used before “otearai” to say “this restroom” in Japanese.
• otearai – お手洗い (おてあらい) : a noun meaning ‘restroom’ or ‘bathroom’ in Japanese. This can also work as plural. Learn more about Japanese plural.
• wa – は : a binding particle working as a case marker or topic marker. In the example, this works after “kono otearai” to make the subject in the sentence.

This is a typical usage of “hiroi”. In this example, it works as the complement in the sentence. Like other adjectives, however, it can also work as a modifier in front of a noun. For example, we can say “kono hiroi otearai” to mean ‘this spacious restroom’ in Japanese. It’s worth knowing, I think. When we want to say “spacious” in Japanese, anyway, this i-adjective is a very good option.

So far, I’ve explained the definition and meanings of “hiroi” and how to use it through the example sentence. In the rest part of this blog post, I will explain its major conjugations. The first one is “hirokunai”.
