: Thanks very much, but if the module simplefonts is obsolete, What should I indicate in the preamble to write with both languages?
Your font setup should be good without trying to load that module (that doesn’t do anything anymore anyway). Just \mainlanguage[es] and \language[agr] (= \agr) where you need it should be enough. You can’t expect ConTeXt to auto-detect your language, even if that maybe would work for Greek. (My texts are usually in German, thus I have \mainlanguage[de] and use \en or \fr to markup foreign quotes. Correct me if I miss something.
When you mark your Greek passages with {\agr ἡ Ἑλληνικὴ γλῶσσα} (or \language[agr] instead of \agr), you should get the right pattern without that setup.
The module simplefonts is obsolete since 2013.
