A discussion has arisen as to how to properly translate the term "fundamento", as well as "fundar".
Suggested interpretations include,
The term "ground" has been suggested since this term has had quite common use in philosophical texts (in metaphysics and in logic) and is used in translations, for example of Heidegger's "Grund". Copleston also uses it, for example when discussing Jasper's existentialism.
An objection to the use of "ground" is that it sounds awkward to the ordinary reader. For example, the phrase, "seeking the ground of reality" might seem quite strange if one is not aware of the technical, metaphysical sense of the term.
Another objection is that "ground" is used in a mathematical and logical context.
The term "foundation" has been suggested, especially because it sounds more natural than the term "ground".
An objection to this is that "foundation" has too broad meaning and lacks the metaphysical connotations of terms like "ground" or "fundament".
The term "fundament" has been suggested and has some use in English philosophical works.
An objection to this is that this word is not of common use in translations of more metaphysical, ontological authors.
With this, I open the floor to discussion. I will add my thoughts after some comments have been made.
