How to say "not enough" as opposed to すぎる？

[ArthurK]

As per the title, how do I say something like "I haven't eaten enough." Is it related to the verb 足りる somehow?
食べるのは足りない?
Thank you!

I have a feeling 食べるのは足りない means "it is not enough to eat." However, I'm not sure...

Another way to say enough is 十分 (ten parts... I think that's a really cool concept in Japanese that ten parts is 100%). It works a little closer to English than 足りる. I'd say 足りる is closer to the usage of ある, or 'there is(n't) enough' in English. (席が足りない、お金が足りない、etc), and as a verb should be considered, 'to suffice.'

So, I haven't eaten= 食べてない or いません depending on your politeness level. Making 十分 an adverb takes a に, and the end result is 十分に食べてない.

I'm about 99% sure that's correct, but I won't complain if one of the native members here tell me some of that's not quite right.

Oh that's interesting! I wonder why popular textbooks don't teach that in conjunction with すぎる. But then Genki, for example, also doesn't explain the different uses of もう and まだ...

まだ食べ足りない is also a possible phrasing (compound verb formed the same way as with すぎる)

you can translate the idea not always the sentence word by word.
If I were you I would say :
まだ食べたい = I still want to eat.

まだ is not wrong, but もっと is more common in that case.

What about the 食べるのは足りない sentence? Does it mean what I think it means (second post)?

"To eat is not enough" (the act of eating alone is insufficient).

量が足りなかった。
お腹はまだ空いている。
まだ腹が減っている。
もうなんかない？
満腹なってない。
Etc etc etc

 

[ArthurK]

Aha, thanks for clearing that out for me. Sounds rather poetic if I may add

は performs as a contrastive marker, thus, the sentence suggests "something is enough but to eat is not enough" (e.g. 飲むのは十分だけど食べるのは足りない).
