Comparisons of Equality are comparisons in which two things or people are equal in some way. For example, “football is as fun as basket”, or “this person has as much money as this other person”.
In this post, we will learn about two types of Comparisons of Equality:
- Comparisons using the formula: “tan… como”
- Comparisons using the formula: “tanto… como”
1. Comparisons using the formula: “tan… como”
We use the formula “tan… como”, with adjectives and adverbs.
Examples (adjective or adverb is highlighted in orange):
Mi hermano es tanalto como yo = My brother is as tall as I am.
Los atletas corren tan rápidocomo un tigre = The athletes run as fast as a tiger.
Sus hermanas son tan listas como ella = Her sisters are as smart as she is.
2. Comparisons using the formula: “tanto… como…”
We use the formula “tanto… como…” with nouns.
In this case, we need to match the word «tanto» to the gender and number of the noun, which results in 4 possible forms of “tanto”:
Examples (nouns highlighted in blue):
Paco tiene tanto dinero como Manuel. = Paco has as much money as Manuel.
La niña ha comido tanta pasta como el niño. = The girl has eaten as much pasta as the boy.
Hay tantos barcos en el mar como ayer. = There are as many ships on the sea as yesterday.
Mi barrio tiene tantas bibliotecas como el tuyo. = My neighborhood has as many libraries as yours.
Special case: “tanto como” without words in between
We can use the formula “tanto como” without placing any word between “tanto” and “como”.
Look at these examples:
María sabe tanto como Ana = Maria knows as much as Ana.
Tengo tantas como tú = I have as many as you. (of something feminine plural)
That is not possible to do with “tan… como”, where you always need an adjective or adverb in between. Otherwise it will turn into the “tanto como” formula.
Look at this exchange, where the answer turns into “tanto como” because we don’t mention the adjective «interesante» again:
¿La película es tan interesante como el libro? = Is the movie as interesting as the book?
Sí, tanto como el libro. = Yes, as much as the book.
