じゅう

じゅう

"じゅう" (juu) means "ten" in English.

Here, 'じゅう' is used in the sense of 'throughout' or 'all over,' attached to '一日' (a day) to imply 'all day long.'

私は一日中働きました。

I worked all day.

In this case, 'じゅう' is used to indicate 'throughout' or 'all over,' combined with '世界' (the world) to express 'all over the world.'

彼は世界中を旅したいです。

He wants to travel all over the world.

Although 'じゅう' is not explicitly present, understanding phrases typically involving 'じゅう' can inform one about spatial or domain-related usage for context.
