When the particle と
is used for 引用（いんよう） (citation) in Japanese, it is regularly partnered with other verbs, to form set phrases. One of these set expressions is と聞（き）いた
, which means ‘I heard that (A)’.
may be used after any phrase expressing the thing that was heard.
I heard that my senpai is going to live in the same apartment that I do.
I heard that winter in Hokkaido is colder than winter in Okinawa.
I heard from a friend that you are good at singing.
I heard that the son of the company president is already a college student.
is often omitted after nouns and な-Adjectives
when used with ときいた
in casual conversation. While this sounds perfectly normal, it is technically not correct Japanese.
I heard that you are bad at swimming, but is that true?
I heard that that mountain over there is the tallest in the world.
