Questions & Answers about Hárið þitt er langt.
Word by word:
- hár – hair
- -ið – the suffixed definite article the, so hárið = the hair
- þitt – your (singular, talking to one person), agreeing with a neuter noun
- er – is (3rd person singular of to be)
- langt – long (neuter form of the adjective langur “long”)
So literally: The hair your is long. In normal English: Your hair is long.
Icelandic doesn’t use a separate word for the. Instead, it adds a suffix:
- hár = hair (indefinite)
- hárið = the hair (definite; -ið is the neuter singular definite ending)
So hárið means the hair, and in this sentence it refers to “your hair on your head” in a general, definite way, just like English “your hair” (we normally think of it as a specific, known thing).
