くらい ②To the extent that, So…that, About the only thing that...

Often, the noun くらい is used as an adverbial particle. This use of くらい (or ぐらい) expresses the limit of something, in a similar way to ほど. This means that it can be translated as 'about (A)', 'so (A) that (B)', or '(A) to the extent of (B)'. Let's take a look at a few examples.

Despite translating in the above ways, we can see that this use of くらい is similar to the standard kanji use 位(くらい), which literally means a 'rank', or 'grade' of something. What this means is that (A) will usually be considered to be at the 'grade' of something that was required in order to cause/allow (B).
