一度(いちど)に (ichido ni)
一度に — all at once
Pattern
-
一度に+V一度に + verb
Meaning
一度 means one time and に marks the manner. 一度に~する means doing something in a single go or at the same time. It fits actions with large amounts or many people: eating a lot, coming in, clearing tasks.
Notes
同時に stresses that two or more things happen at once; 一度に stresses doing it all in one go. In negatives (一度にはできない) it means 'it can't be done in one go.'
Examples
-
そんなに一度(いちど)にたくさん食(た)べられません。
Sonna ni ichido ni takusan taberaremasen.
I can't eat so much all at once.
-
大勢(おおぜい)のお客(きゃく)が一度(いちど)に店(みせ)に入(はい)ってきた。

-
たまった用事(ようじ)を一度(いちど)に片付(かたづ)けてしまおう。
Tamatta yōji o ichido ni katazukete shimaō.

Common mistakes
- 一度に is different from plain 一度 (once, as in 日本に一度行った).
- It does not mean 'only one time' but 'together, in one go.'
