> Strictly, cognates are words with a shared origin. For a learner, the most useful ones also kept a similar meaning: *information → información*, *animal → animal*, *artist → artista*. Five patterns are worth recognising straight away: English **-tion** often maps to Spanish **-ción**, **-ity** to **-idad**, **-ous** to **-oso**, **-ist** to **-ista**, and **-al** to **-al**. Use those patterns to guess while reading, not to manufacture words while speaking: check the word when the meaning matters, because similar-looking words can have different meanings.

## The patterns worth recognising

You do not need to memorise a history of English and Spanish to use these. The ending tells you where to start, and the sentence tells you whether the guess makes sense.

*Five common correspondences*

| English ending | Spanish ending | Examples |
| --- | --- | --- |
| -tion | -ción | information → *información*; nation → *nación* |
| -ity | -idad | curiosity → *curiosidad*; university → *universidad* |
| -ous | -oso | famous → *famoso*; curious → *curioso* |
| -ist | -ista | artist → *artista*; tourist → *turista* |
| -al | -al | animal → *animal*; hospital → *hospital* |

These are correspondences, not translations of every word with that ending. They work best when you recognise the stem too: *nación* is a small step from nation, and *curiosidad* from curiosity. If the stem is unfamiliar, the suffix alone will not rescue the meaning.

## Use them to read, not to invent

A good cognate lets you keep moving through a sentence. A guessed word you make up yourself can do the opposite. In particular, do not simply add *-ción* to an English word and assume the result exists. A job application is *una solicitud*, not *una aplicación*. *Aplicación* exists, but it is not the word you want for that job application.

The safe order is: recognise a word in a real sentence, decide whether the familiar meaning fits, and check it if the sentence matters or something feels off. That gives you the benefit of the resemblance without turning it into a habit of guessing.

## The details that change when you use the word

- **The accent in *-ción* matters.** *Información* is stressed on the *ó*. In the plural, *informaciones*, the written accent disappears because the normal Spanish stress rules no longer require it.
- **Nouns in *-ción* and *-idad* are normally feminine.** *La información*, *la nación*, *la curiosidad*, *la universidad*. Learn the article with the noun.
- **People in *-ista* usually keep the same form.** *El artista* and *la artista*; *el turista* and *la turista*. The article carries the gender, not a change from *-o* to *-a*.
- **Adjectives in *-oso* agree.** *Un libro curioso*, *una historia curiosa*; *un hombre famoso*, *una mujer famosa*.
- **Words in *-al* take *-ales* in the plural.** *El animal*, *los animales*; *el hospital*, *los hospitales*. Spanish *hospital* also has a silent *h* and its stress at the end, unlike the English word.

## When the familiar meaning is the wrong one

A false friend looks reassuring and then changes the sentence. Some are related historically but have drifted apart; others merely look alike. For a reader the distinction matters less than the habit of checking. These are useful defaults, not claims that each word has only one sense:

*Three pairs worth learning together*

| The familiar-looking word | Its usual meaning | For the English word, use |
| --- | --- | --- |
| *sensible* | sensitive, when describing a person | *sensato* — sensible |
| *embarazada* | pregnant | *avergonzada* — embarrassed |
| *librería* | a bookshop | *biblioteca* — a library |

*Librería* can also mean a bookcase or a personal library, and *embarazada* has a secondary sense of being inhibited or uncomfortable. That is exactly why the practical rule is “check the word”, not “learn a new absolute”. The [false friends guide](https://learnwithkin.com/spanish/false-friends) has the longer list and the pairs to learn.

## How to use cognates without collecting bad guesses

- **Let the sentence vote first.** If the familiar meaning fits the whole sentence, keep reading. You have just used a cognate for what it is good for.
- **Check when the meaning changes something.** A name, a number, a negation or a word that changes the point of the sentence is worth a dictionary lookup.
- **Keep the article and the stress with the word.** *La información* is more useful than a bare translation of information. Knowing how the word behaves is part of knowing it.
- **Meet the word again in another sentence.** One successful guess is recognition. Several encounters in different contexts are what make the word available to you.
- **Learn false friends as pairs.** *Sensible / sensato*, *librería / biblioteca*. The contrast is easier to retrieve than a warning attached to one word.

## Questions

### Are cognates always identical in Spanish and English?

No. Some are identical in spelling, like *animal*, while others follow a pattern, like *nation → nación* or *curiosity → curiosidad*. Pronunciation, stress and grammar can all differ even when the spelling is close.

### Can I turn any English -tion word into Spanish with -ción?

No. The pattern is a recognition aid, not a word factory. Many common words work, but some take another form and some do not exist in Spanish. Check before using a guessed word.

### Are -ción and -idad nouns feminine?

Normally, yes: *la información*, *la nación*, *la curiosidad*, *la universidad*. It is worth learning the article together with the noun rather than as a separate fact.

### Is artista masculine or feminine?

Both. *El artista* and *la artista* use the same word; the article changes. Many words for people ending in *-ista* work this way, including *turista* and *periodista*.

### Are all similar-looking words cognates?

No, and even words with a shared origin can have different modern meanings. That is why “cognate” describes an origin, while “useful cognate” for a learner usually means that the meaning stayed close too. Check the word when the resemblance seems too convenient.
