Learn Spanish (Latin America): ¡Qué narizota y qué orejotas tiene ese villano! - What a big nose and what big ears that villain has!

Both nariz (nose) and oreja (ear) are feminine nouns. To make them augmentative (meaning "big" or "large"), we add the feminine suffix -ota. For oreja, we drop the final vowel before adding the suffix to get orejota (and add -s for the plural). For nariz, which ends in a consonant, we just add -ota directly to the end.

Why doesn't the 'z' in narizota change to a 'c', like it does in the plural narices?

In Spanish spelling, 'z' changes to 'c' only when it comes right before the vowels 'e' or 'i' (which is why nariz becomes narices). Because the augmentative suffix -ota starts with an 'o', the 'z' gets to stay exactly as it is!

The translation says "What a big nose." Why isn't there a word for "a" (una) after Qué?

In English, we use "What a..." for singular nouns in exclamations. Spanish doesn't use the indefinite article (un or una) after qué in this type of phrase. You just attach qué directly to the noun: ¡Qué narizota! (What a big nose!).

Do the -ota endings here just mean the villain's features are physically big?
