Questions & Answers about Þau komu ómeidd heim.
Þau is the neuter plural form of they.
In Icelandic, þau is often used:
- for a mixed-gender group
- for children
- when the group is referred to in a more general or unspecified way
- when the antecedent is a neuter plural noun
So in this sentence, þau does not necessarily mean the people are neuter in any real-world sense. It is just the correct grammatical form in certain contexts.
For comparison:
- þeir = they, masculine plural
- þær = they, feminine plural
- þau = they, neuter plural
Komu is the 3rd person plural past tense of koma, which means to come.
So:
- koma = to come
- kom = came, singular
- komu = came, plural
Here it agrees with þau, which is plural, so komu is the correct form.
