**X times as …**

Pattern: `[adjective] + gấp đôi / gấp ba (lần) + [comparison]`

Level: B1 (our estimate) · Register: everyday

Typed without accents: gap doi, gap … lan

*Gấp* means "times" when you multiply an amount: *gấp đôi* is twice as much, *gấp ba* three times, *gấp mười* ten times. For twice, the everyday form is *gấp đôi*, with *đôi* (a pair); *gấp hai lần* also turns up, mostly in figures and reports. From three up, use the plain number.

Put it after the adjective, then what you compare with: *Nhà này lớn gấp đôi nhà cũ.* This house is twice as big as the old one. When the comparison is clear, leave it out: *Ở đây tiền nhà mắc gấp ba.* Rent here is three times as much. *Lần* (times) can follow the number, especially in writing and with bigger numbers: *gấp mười lần*.

It can also follow a noun, as an amount: *Lương anh ấy gấp đôi lương em.* His salary is double mine. After *tăng* (go up), it means "double" or "triple": *Năm nay khách tăng gấp đôi.* This year we've had twice as many customers.

For "half as much", Vietnamese uses *một nửa* (half) instead: *Giá ở đây chỉ bằng một nửa.* Prices here are only half as much.

## A common mistake

✗ Nhà này lớn hai lần nhà cũ.

✓ Nhà này lớn gấp đôi nhà cũ.

For "times as big", *gấp* goes before the number. *Hai lần* on its own means "twice" as in "on two occasions".

## Examples

- Nhà này lớn gấp đôi nhà cũ. — This house is twice as big as the old one.
- Lương anh ấy gấp đôi lương em. — His salary is double mine.
- Saigon: Ở đây tiền nhà mắc gấp ba. | Hà Nội: Ở đây tiền nhà đắt gấp ba. — Rent here is three times as much.
- Năm nay khách tăng gấp đôi. — This year we've had twice as many customers.
