tan

/tahn//tan/

adverbA1general

Use 'tan' primarily in exclamations to express intensity or degree, often when comparing or emphasizing a quality.

A visual comparison showing two sunflowers that are equally tall, representing the Spanish word 'tan' used for comparisons of equality.

Examples

¡Qué día tan maravilloso!

What a wonderful day!

Mi hermano es tan alto como mi padre.

My brother is as tall as my father.

El pastel está tan rico.

The cake is so delicious.

Estaba tan cansado que me dormí inmediatamente.

I was so tired that I fell asleep immediately.

The 'as... as...' Formula

To say two things are equal, use this magic formula: tan + [describing word] + como. For example, 'El libro es tan interesante como la película' (The book is as interesting as the movie).

Making Words Stronger

You can use 'tan' by itself before a describing word (like 'good' or 'fast') to make it stronger, just like 'so' in English. For example, 'Estoy tan feliz' (I am so happy).

Using 'Tan' vs. 'Tanto'

Mistake: “Tengo tan dinero como tú.”

Correction: Tengo tanto dinero como tú. Use 'tan' for describing words (adjectives/adverbs). Use 'tanto' when talking about the amount of a thing (a noun). 'Tan' never changes, but 'tanto' changes to 'tanta', 'tantos', or 'tantas' to match the thing it describes.

así

/ah-see//aˈsi/

adverbA2general

Use 'así de' followed by an adjective to emphasize a specific quality or characteristic, similar to 'so' or 'this' in English.

A very small cartoon character standing next to a massive, oversized, brightly colored strawberry, emphasizing its extreme size.

Examples

Nunca vi un coche así de rápido.

I've never seen a car so fast.

Nunca vi un perro asi de grande.

I've never seen a dog so big.

¿Por qué estás asi de preocupado?

Why are you so worried?

Una persona asi no puede ser presidente.

A person like that (such a person) can't be president.

The 'así de' Combo

When you use 'asi' to describe 'how much' of something, it's almost always followed by 'de'. Think of 'asi de' as a single chunk that means 'this...' or 'so...'. For example, 'asi de fácil' means 'this easy' or 'so easy'.

Using 'asi' vs. 'tan'

Mistake: “Using 'asi' before an adjective like you would in English: 'un perro asi grande'.”

Correction: Say 'un perro asi de grande' or 'un perro tan grande'. 'Asi' needs the 'de' in this situation, while 'tan' doesn't.

tal

/tal//tal/

adjectiveB1general

Use 'tal' to refer to a specific, often noteworthy, instance or type of something, similar to 'such a' or 'that particular'.

A Spotlight Word

Think of 'tal' as a spotlight you shine on a noun to say 'this kind of' or 'a noun like this'. It often shows surprise, admiration, or disapproval.

Plural Form

'Tal' changes to 'tales' when the noun it describes is plural. For example: 'tal problema' (one problem) becomes 'tales problemas' (many problems).

Don't Add 'Un' or 'Una'

Mistake: “No quiero un tal problema.”

Correction: No quiero tal problema. 'Tal' already includes the idea of 'a' or 'an', so you usually don't need to add 'un' or 'una' with it.

Choosing between 'tan' and 'así'

Learners often confuse 'tan' and 'así de' because both can express intensity. Remember, 'tan' is a general intensifier, especially in exclamations ('¡Qué tan bonito!'), while 'así de' specifically modifies an adjective to describe 'how' something is ('tan grande' vs 'así de grande').
