word indicating a time
. When it is suffix
ed to numbers by itself, it usually means "o'clock
". However, it also conveys general notions of time
and is used in words like ichinichi
(all day). Ji
is not used alone -- it's basically a suffix
Ima wa san-ji desu.
It's now 3:00.
Nan-ji ni okimashita ka.
What time did you wake up this morning?
Ichinichi literally means "one day". However, ichinichi-ji means "all day", i.e. all the hours in the day.
Kyoo wa okimasen yo. Ichinichi-ji nemashita yo.
I didn't wake up today...I slept all day!
Written ji, with the kanji for "time; hour".
