if you use a question word it can also be used as no- (何も-nothing 誰も-no one)

the example sentence for adding も to question words is using the wrong verb, it should be いない not ない.

Hmmm, can't 「も」 also simply mean [even]?　I think that's where some of the other expressions that incorporate 「も」 (and for which grammar pages already exist) come from, for example: そこまでしなくて[color=blue]も[/color]いい。 [i][color=blue]Even[/color] if you don't do it until there, it's OK.[/i] [b]You don't have to go that far.[/b] これを使って[color=blue]も[/color]いい？ [i][color=blue]Even[/color] if I use this, is it ok?[/i] [b]May I use this?[/b] But then, of course, it can be used by itself, following nouns and such: 彼女はお茶の一杯[color=blue]も[/color]出そうとしなかった。 [b]She didn't [/b][color=blue][b]even[/b][/color] [b]offer me a cup of tea.[/b] I think that this [even] meaning of 「も」 is the key to understanding the particle's use in sentences like this one: いままで見たこと[color=blue]も[/color]ないようなとっても大きな大きな蕪です。 [b]It is a gigantic turnip the likes of which he had never [color=blue]even[/color] seen before.[/b] Now, in English you can leave the word [even] out of the above sentence, because all it is doing is adding emphasis. Similarly, I think that you could have said 「見たこと[color=blue]が[/color]ない」 in the Japanese version, and the overall meaning wouldn't have really changed. 「も」 is just acting as an emphasis particle in this case, just as [even] is. What do you think?

This covers the first two examples: http://www.renshuu.org/index.php?page=grammar/individual&id=107

Ok, I definitely feel like it could belong on the page. Definition: (not) even [A] Usage structure: [N] も, [Noun clause] も, [Verb stem] も しない What do you think? Edit: note that the 'not' version is brought out when followed by a negative verb/statement.

Bit different in terms of usage, actually. ても/でも is used with verbs, generally in the sense of "even if": 雨が降っても行きます。 I'll go even if it rains. でも also appears after nouns and な-adjectives with the same usage, as a form of だ. 学生でもできる仕事 work even a student can do And でも can also be used when making suggestions or invitations to show that you'd be open to other alternatives: お茶でも飲む？ Want some tea (or something else to drink?) The first usage of も here is used to show extent, and it implies you think doing something to that degree is surprising. 6時間も勉強したの？ You studied for six (whole) hours?! も isn't used in either the gentle suggestion or the "even if" sense.

When using も, can't you also create the meaning of anything, anywhere, and anyone? Such as 何もいいよ: Anything is good. Isn't this why the company DoCoMo　chose their name, meaning anywhere?

Thank you! :]

Alright - so this is not on here yet, but I'll add it! Please check now.

Thanks!

under the last/newest usage, you can also use ~くて for い adjectives - like 寒くても暑くてもない
