Learn French: Je cherche un autre chemin. - I am looking for another path.

In French, most adjectives go after the noun. However, a small group of common adjectives goes before the noun. These often describe Beauty, Age, Number, Goodness, or Size. Autre (other) acts like a number or quantity adjective here, so it steps in front of the noun to make un autre chemin.

Why isn't there a word meaning for after cherche?

The French verb chercher means to look for or to seek all by itself. You never need to add a translation of for (like pour). You just name what you are seeking directly: Je cherche un autre chemin.

Do I pronounce the n in un when saying un autre?

Yes! Normally, the n in un is silent and just makes the vowel nasal. But because autre starts with a vowel sound, you connect the words by pronouncing the n to make it flow smoothly. This spoken connection is called a liaison.

Is chemin a masculine or feminine word?

It is masculine, which is why we use un instead of une. Notice that autre ends in an e, but its spelling is exactly the same for both masculine and feminine nouns. If you were looking for another street (which is feminine), you would say une autre rue.
