solo (feminine sola) for emphasis on single/only

Common mistakes and how to avoid them

Quick tips for remembering forms

Keep these simple rules in mind when you form questions about one part.

Match uno/una to the gender of the noun.

Use solo or único to stress only one available item.

Place polite words like por favor at the start or end for natural speech.

When pointing, combine demonstratives (este/esta/ese/esa) with the noun, not with a separate uno.
