Romper vs. Quebrar

Romper vs. Quebrar
 

Here are a couple more verbs for you, Perikles. :)

Differences? Similarities? Nuances?

Generally speaking, quebrar is something like glass or some kind of surface, that breaks.

on the contrary if it is a toold that you are hanlding like a wrench and say you exert force on it and the handle breaks that's romper.

Difficult to explain, but that's more or less how I use it.

Also when an engine breaks, that for me is "echar a perder"

So, would it be okay to consider (generally speaking) that "quedar" is more passive (something breaks), while "romper" is more active (someone breaks something)? Thanks, Chileno!

Probably that's right, in the case of the "romperse" or "quebrarse" (as more pasive than "romper/quebrar")

I give you the examples from Oxford bilingual, if that helps. (I put few bracketed translations of my own... but if you have any question on the examples, let us know...)

Thanks, Ookami ... are there situations in which one is used more often than another?

Whoops - Pablo, you and I clicked "submit" at the same time. I will go back and read your thread, and the moderators will probably have to merge my back-to-back posts. :)

So, Pablo - it almost sounds like "quebrar" can be used for something that could potentially be put back together or mended, where as "romper" would be used for something destroyed by its breakage...?

Mmmm... (I thought I had seen Ookami's post with the DRAE definitions... but he may be modifying it?)
As he said both terms are very close synonyms... I believe "romper" is more general term with more usages... but in the case of a "plate" or a "glass"... it seems hard to put back together any way...

Yeah - where did that post go? Ookami???

I think the above covers it all without my dictionary. :)

Don't worry, Sir Perikles, I have many more verb-y questions for your dictionary. :)
