Learn Icelandic: Það er ekki lengur til. Handritið er glatað. - It is no longer available. The manuscript is lost.

The phrase vera til is a particle verb meaning to exist or to be available. In Icelandic, the particle (here, til) usually gets pushed to the end of the clause, making way for adverbs like ekki lengur (no longer) to come directly after the main verb.

Is ekki lengur the normal way to say not anymore?

Yes. It literally translates to not longer. Whenever you want to say that something does not happen anymore or is no longer the case, you use ekki lengur right after the verb.

How is the word handritið built?

It is a compound of hönd (hand) and rit (a piece of writing), plus the neuter definite article -ið (the). So it literally means the hand-writing, which is exactly what a manuscript is!

Why is the word for lost spelled glatað instead of the dictionary form glataður?

Adjectives and past participles have to match the gender of the noun they describe. Because handrit is a neuter noun, the past participle drops the masculine -ur ending and takes the neuter -ð ending to become glatað.
