Questions & Answers about Mis tapones de oído están en la mesa.
Because tapones is plural.
In Spanish, the possessive adjective has to match the number of the thing possessed, not the owner.
- mi tapón = my earplug
- mis tapones = my earplugs
Even though there is only one my, the noun is plural, so Spanish uses mis.
Because the sentence is talking about more than one earplug.
The singular form is:
- tapón = earplug
The plural is:
- tapones = earplugs
Spanish usually forms the plural by adding -s if the word ends in a vowel, or -es if it ends in a consonant. Since tapón ends in -n, it becomes tapones.
Also notice the written accent disappears in the plural:
- tapón
- tapones
