Questions & Answers about Þeir voru fyndnir í gær.
Why do we use voru in this sentence?
Voru is the past tense of vera (to be) for "they". You use it with the plural pronouns þeir, þær, and þau. If the sentence was about "we" (við), you would use vorum instead.
Does þeir just mean "they" in general?
Not exactly! Icelandic has three words for "they" depending on gender. Þeir specifically means "they" for a group of males (or grammatically masculine words). If the group was all female, it would be þær, and a mixed-gender group would be þau.
Why does the word for funny end in "-nir" (fyndnir)?
Adjectives in Icelandic change their endings to match the word they describe. Because the subject þeir is masculine and plural, the dictionary form of the adjective fyndinn (funny) changes to its masculine plural form, which is fyndnir.
Why is "yesterday" written as two words (í gær)?
In Icelandic, "yesterday" is expressed as a short phrase that literally translates to "in yesterday". You will always use the two words í gær together to mean "yesterday".
