Particles that indicate surprise [も/まで]


It is my understanding that using the either the particle も or まで can both
indicate surprise that the noun is included within some context.

(I'm not that advanced in Japanese yet so I apologise for mixing English and
Japanese into the example. Hopefully I got the idea across).

Ex/

English: "Even children own phones!"

Japanese: "childrenも phonesを own!" v.s. "childrenまで phonesを own!"

Are these particles interchangeable in this context?




In this case, using 「まで」 would be just fine, but using 「も」 by itself would be
a little too weak to serve the purpose of expressing one's surprise.

The most often used (therefore, most natural) particle choices here would be:

> 「こども + **まで/までも/でも/さえも/でさえも** + 携帯{けいたい}を持{も}っている。」

Among all those choices, 「まで」 and 「でも」 are on the informal side, and 「でさえも」
would be the most formal and emphatic.
