To start of, let me clarify what I "know" about "uno", "un", and "una":
- Uno is used when the object is not mentioned.
- Un is when the object is mentioned.
- Una is the feminine form of "Un".
(Again, please correct me if I'm wrong.)
With that said, how would these phrases be translated in Spanish. More importantly if we have a phrase where the amount is a two digit number or higher- except eleven- ending with 1 (i.e. 21, 41, 101), would the word "uno" change in certain conditions?
Phrases in question:
- "En julio hay treinta y un días." translates to ".... thirty-one days."
- "Francisco tiene veinte y un años." translates to "... 21 years" (I especially have trouble convincing myself that this is the correct way even though I hear it as "....y uno años."
- "Las frutas cuestan cincuenta y un centavos" translates to "....fifty-one cents" (Again, hard to believe, so please clarify).
