"The woman studies."
I learned domina for "woman" but it was rejected here; should I report it as an alternate solution?
Domina should rather be a lady, mistress, not just any woman. The same for dominus.
Studere: please check http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0060%3Aentry%3Dstudeo. There is not really a word for ‘to study’ in classical Latin. You could use studere, but then you’d need an object with it.
Yes, thank you, I got that. But studeo is the form they use in the dictionary entry.
Studere was certainly used As study in medieval Latin and is used that way in the modern way. The Romans may not have used it quite this way, but that doesn't mean there is no value in this sentence. I tell my students studete!.
