Learn Icelandic: Kápan er svolítið stór.

svolítið is an adverb of degree meaning "a little" or "somewhat". It tells us how big the coat is. Because it is acting as an adverb here, it is frozen in this form and does not change its ending to match the gender of the coat.

Is svolítið made up of two different words?

Yes! It is a combination of svo (so) and lítið (little). When put together, they create a very common adverb used to soften adjectives, much like saying "a bit" in English.

Why doesn't the adjective stór end in anything special, like stórt?

Adjectives must match the noun they describe in gender, number, and case. The noun kápan (the coat) is feminine and singular. For the adjective "big", the feminine singular form is simply stór. The neuter form is stórt, which you would use if describing a neuter noun like hús (house).

I learned that "the" is an ending in Icelandic. How does that work in Kápan?

You are right! In Icelandic, the definite article (the word for "the") is usually attached to the end of the noun. The basic feminine word for coat is kápa. To say "the coat", you just add the feminine suffix -n to get kápan.
