Presume/Assume/Suppose

N001
I was seeing the meaning and difference between "presume" and "assume".

So, I take the conclusion that we use assume when we have less evidences and presume when we have more evidences. But then I remember the other verb, suppose and I got lost. Now, my question is: What's the difference betwteen suppose and these two verbs?

Thanks in advance.

assume - to believe that something is true, even though no one has told you or even though you have no proof (Macmillan Dictionary)
presume - to think that something is true because it is likely, although you cannot be certain (Macmillan Dictionary)
suppose - to believe that something is probably true, based on your experience, your knowledge, and any other information that you have (Macmillan Dictionary)

In fact, they are very similar. When you assume something, you are not sure about it and you have no proof. I guess there's no difference between "presume" and "suppose", just like it's in Portuguese. According to Houaiss Dictionary:

Presumir - Tirar uma conclusão antecipada, baseada em indícios e suposições, e não em fatos comprovados; conjecturar, supor.
Supor - admitir hipoteticamente

So, we can conclude that presume and suppose are synonymous.

Nicole, all three words have to do with accepting something as true, for various purposes and under various circumstances, but their respective uses are not really correlated to different 'amounts' of evidence.

It's in the usage that we find specific applications. In math, we 'assume' something to be true. In law, we 'presume innocence' until guilt is proven. In everyday language we 'suppose' all kinds of things, meaning we think they're probably true. Etc.

How best to use them is more a matter of checking dictionary usage samples, Google examples, etc.
