多久

多久 means 'how long' and is used to ask about the duration of time. It is commonly used in questions to inquire about the length of time something takes or has taken.

The character 多 (duō) means 'more' or 'many,' and 久 (jiǔ) means 'long' or 'a long time.' Together, they form a question word that asks about the extent of time.

多久 is often used in daily conversations to ask about the time needed for an action, such as how long a task will take or how long someone has been doing something. It can also be used in expressions like 多久之后 (how long after) or 多久没见 (how long since we last saw each other).
