Questions & Answers about Mi pantufla es cómoda.

Why do we use ser in the sentence Mi pantufla es cómoda and not estar?

We use ser to describe inherent or defining qualities of things. Here cómoda expresses a permanent characteristic of the slipper itself. If you wanted to say a person feels comfortable at a given moment, you would use estar: Estoy cómodo (I am comfortable).

Why does cómoda have an accent mark on the ó?

Spanish stress rules require a written accent when the stress falls on the third-to-last syllable in words that end in a vowel, n, or s. có-mo-da is stressed on the first syllable (antepenult), so we mark the ó.

Shouldn't slipper be pantuflas in the plural since we have two feet?

If you refer to the pair, you would indeed say Mis pantuflas son cómodas. In our sentence we’re talking about one slipper (mi pantufla). Spanish allows both forms depending on whether you focus on one or the pair.

Why is pantufla feminine and how does that affect the adjective?

Most Spanish nouns ending in -a are feminine. Adjectives must agree in gender and number with the noun they modify. Because pantufla is feminine singular, the adjective is cómoda (not cómodo or cómodos).
