What are three different cases when Spanish uses the definite article in the construction of a sentence while English doesn’t?

Question

I used 1.) before a noun, 2.) professional titles, and

3.) I cannot find this ANYwhere in my notes. Thanks in advance!

Answer 1

Before names of people you're not speaking to. Like this: "El Señor Rodríguez está enfermo." I call this "the gossip case" .

Well, that's already one of the answers; plus you don't capitalize señor unless it's the first word of the sentence or it's abbreviated. - NoniB, MAY 6, 2010

It didn't look like one of your answers to me. - MacFadden, MAY 6, 2010

Answer 2

Before days of the week if you are going to say "on".

Example - "el lunes"- "on Monday"..."los lunes" - "on Mondays".
