1. ~くらい / ~ぐらい (About / At least / As little as...)
* Na-adjective だ -> な
Meaning: Expresses degree: “to the extent of / about / at least...”.
✓ In the usage highlighted here, the speaker often presents something as a small, minor, or minimum degree: “something as little as that / at least that much.”
✓ It can follow a noun or a clause. くらい and ぐらい are basically equivalent; ぐらい is especially common in conversation.
✓ Do not treat ぐらい after nouns as an obligatory rule.
2. ~など / ~なんか / ~なんて (Things like... / Something like...)
Meaning: Presents a person, thing, or matter as an example; in this usage it often carries a dismissive, belittling, or self-deprecating nuance.
✓ なんか / なんて are more conversational than など. など can also be used in formal/written contexts depending on its function.
✓ なんて has other uses as well, so it should not always be interpreted as contemptuous.
✓ The following clause often contains an evaluation such as “not worth worrying about,” “no need to...,” or self-deprecation.
3. ~まで / ~までして / ~てまで (Even to the point of... / Going so far as to...)
Vて + まで
Meaning: Even... / go so far as to... / even do... in order to...
✓ Nまで gives an unexpected or extreme example: “even N...”.
✓ Nまでして / Vてまで emphasize going so far as to use an exceptional action or means to achieve a purpose.
✓ They often convey surprise, criticism, or strong evaluation, but not necessarily literal disbelief.
4. ~として~ない (Not even a single... / Not one...)
Meaning: Completely negates something, emphasizing that not even the smallest possible unit—such as one person, one time, or one thing—exists or occurs.
✓ Always used with the minimum counting unit, such as one person, one time, or one item.
✓ The following clause must be completely negative.
5. ~さえ (Even... / As long as...)
Meaning A: Gives the lowest-level example and implies that if even that is true, then higher-level cases naturally follow.
✓ The following clause does not express the speaker’s will.
Meaning B: When used with a condition, it means that satisfying this one minimum condition is enough and the other conditions no longer matter.
6. ~てでも (Even if I have to... / By any means necessary...)
Meaning: Even if it means doing... / even by resorting to...
✓ Used when someone is willing to use an unusual, difficult, or fairly extreme means to achieve a goal.
✓ The following clause often expresses strong will, desire, determination, or necessity.
✓ The means does not have to be something one would “never normally do”; the focus is strong determination.
