What's the difference between すべてand全部

[daboy1993]

I've seen both used under almost the same context, so when do I use each?

[NileCat]

They are the same in meaning.
ぜんぶ sounds more casual than すべて.
For instance, children under 10 wouldn’t use すべて, generally speaking.
And you wouldn't see ぜんぶ much in academic essays.

Well, I don’t know if it worth replying, though...

"すべて" has the meaning of "complete" and "全部" are all part of something.

That’s only half-right.
全部 has the meaning of "complete" as well and すべて can mean "all part of something".
