Questions & Answers about Mælitækið datt eitthvert, skínandi bjart.
Why do we use eitthvert here instead of einhvers staðar?
The verb að detta (to fall) involves motion towards a destination. English often just says "somewhere" for both motion and location, but Icelandic strictly distinguishes them. You must use eitthvert (to somewhere) because the instrument is moving to a new place, whereas einhvers staðar (at/in somewhere) is only used for stationary positions.
If the instrument had fallen from a hidden spot instead, how would the sentence change?
You would replace eitthvert with the adverb for motion from somewhere: einhvaðan. The sentence would become: Mælitækið datt einhvaðan (The measuring instrument fell from somewhere).
Does the present participle skínandi change its ending to match the neuter noun mælitækið?
No. Present participles in Icelandic (words ending in -andi) are invariable. They never change their endings for gender, number, or case, so skínandi stays exactly the same whether it describes a neuter, masculine, or feminine noun.
Why does bjart (brightly) end in -t?
In Icelandic, adverbs derived from adjectives are generally just the neuter singular nominative form of that adjective. Therefore, the adjective bjartur (bright) becomes the adverb bjart (brightly). Notice how skínandi pairs with it here to create the vivid phrase "shining brightly" or "brilliantly bright".
