Translation guide
To express approximation in Japanese, you can use adverbs, suffixes, or particles depending on whether you're talking about quantities, time, or general vagueness. The most common and versatile word is 約 (yaku), but other options like くらい/ぐらい (kurai/gurai) and ほど (hodo) are also essential for natural speech.
Expressing that a number or amount is not exact, often used in formal or written contexts.
Placed before a number or quantity. Common in both spoken and written Japanese, neutral formality.
Approximately 100 people participated.
It's about 2 kilometers from here to the station.
Similar to 約 but slightly more formal or literary. Often used in written language or formal speech.
Means 'almost' or 'nearly', implying a very close approximation. Often used when the difference is negligible.
Expressing a rough estimate in everyday conversation, often with a sense of 'more or less'.
Attached after a quantity, time, or degree. くらい and ぐらい are interchangeable, though ぐらい is more common after certain sounds. Very common in casual speech.
Indicating that something is not exact but generally true, often used with adjectives or verbs.
Specifically for giving approximate times, dates, or durations.
Used after a time expression to mean 'around' or 'about'. ころ is used after words, ごろ after specific times. Very common.
Both mean 'approximately' or 'about', but くらい is more common in casual speech, while ほど is slightly more formal and often used in written language or polite conversation. ほど can also imply an extent ('as much as'), so context matters.
