Questions & Answers about ¿Te gusta aquella corbata azul?
Why use aquella instead of esa if both mean "that"?
Why is the word aquella rather than aquel?
Pointing words have to match the gender of the noun they describe. Because corbata (tie) is a feminine noun, we use the feminine singular form aquella. If we were pointing at a masculine noun like traje (suit), we would use aquel.
Why is the verb gusta instead of gustas when asking "Do you like"?
Why does aquella go before the noun, but azul goes after it?
In Spanish, words that point out which specific object you mean (like este, esa, or aquella) always go in front of the noun. However, words that describe what the object looks like (like colours, such as azul) almost always come after the noun.
