〜という〜
… called, named …machine translation
FormationName + という + noun
When mentioning a name the listener may not know, you sandwich it between という and a noun for the category: ダナンという町 (a city called Da Nang), 「さくら」という店 (a shop called Sakura). The literal meaning is "(is) called" — it's the very verb 言う from the 〜と言う lesson.
This pattern signals "this is a proper name you may never have heard," so it's perfect for introducing your hometown or talking about movies, books, dishes… Conversely, with names everyone knows, it's unnecessary: 東京という町 sounds redundant; just saying 東京 is enough.
To ask for a name, use 何という: これは何という花ですか (what is this flower called?). In casual speech, という often shortens to っていう or って.
Examples
私はダナンという町から来ました。
I come from a city called Da Nang.
「さくら」という店でケーキを買いました。
I bought a cake at a shop called Sakura.
これは何という花ですか。
What is this flower (what is it called)?
