Learn Spanish (Spain): Me parece que tienes razón. - It seems to me that you are right.

In Spanish, being right is expressed with the verb tener (to have) followed by the noun razón (reason). You literally say "you have reason". It works just like other Spanish expressions of feeling or state, such as tengo hambre (I am hungry, literally "I have hunger").

Why is it "me parece" instead of something like "yo parezco"?

Here, the verb parecer (to seem) is used similarly to the verb gustar (to like). The pronoun me means "to me", and parece is in the "it" form. So, me parece literally translates to "it seems to me".

In English I can drop the word "that" and say "It seems to me you are right." Can I drop "que" in Spanish?

No, you cannot drop it in Spanish. While English often skips the connecting word "that" between two parts of a sentence, Spanish requires the word que to link them together.

Why is it just "razón" and not "la razón"?

When you want to say "to be right", it is a set expression: tener razón. You do not use the article la. If you were to say tienes la razón, it would sound more like you possess "the absolute truth" or "the specific reason", which is not what you mean here.
