Approximately / To the Extent That
JLPT N5ParticleNeutral
〜くらい (also written 〜ぐらい) is a versatile particle that attaches to nouns, numbers, verbs, and adjectives to express approximation or degree. In its most basic use, it means "about" or "approximately" when attached to quantities, amounts, or time expressions. Beyond approximation, it can indicate the extent or degree of something, often translatable as "to the extent that" or "as … as." The two forms くらい and ぐらい are interchangeable in modern Japanese with no difference in meaning or formality, though ぐらい tends to be slightly more common in casual speech. Compared to ほど, which also expresses degree, くらい tends to feel lighter and is more natural for simple approximations of quantity, while ほど often carries a stronger nuance of proportionality or extent. Compared to ばかり, which can also mean "about" with quantities, くらい is more broadly used and does not carry the connotation of "only" or "nothing but" that ばかり sometimes implies.
Functions
#1 Expressing approximate quantity or amount
Structure
Number / Counter + くらい・ぐらい
毎日三十分ぐらい歩きます。
Here ぐらい attaches directly to the time expression 三十分 to indicate that the duration is approximate, not exact. This is the most common and fundamental use of くらい・ぐらい, appearing naturally with numbers, counters, and time words. The speaker is not claiming to walk exactly thirty minutes — the particle softens the number into an estimate.I walk for about thirty minutes every day.

Common mistakes
A common mistake is thinking that くらい and ぐらい are different in meaning or formality — they are fully interchangeable. Learners often confuse くらい with ごろ, but ごろ is used only for approximate points in time (三時ごろ = around 3 o'clock), while くらい is used for durations and quantities (三時間くらい = about 3 hours). Another frequent error is using くらい where ほど would be more natural in formal or proportional expressions; for instance, in the pattern "the more … the more …" (ほど is required, not くらい). Finally, beginners sometimes forget that when くらい modifies a following noun, the particle の is needed between them, as in 三十分ぐらいの休み.
