Questions & Answers about Hafið er kalt.
What does hafið mean and why does it have the suffix -ið?
hafið is the definite form of the neuter noun haf, meaning the sea. In Icelandic, the definite article is not a separate word but a suffix attached to the noun. For neuter singular nouns like haf, the suffix is -ið (so haf + -ið = hafið).
What case, gender and number is hafið in, and how do I know?
hafið is nominative singular neuter.
- It’s the subject of the sentence, so it takes the nominative case.
- haf is a neuter noun, and the -ið ending marks it as definite, singular, and neuter.
What is er in this sentence and how is it used?
er is the third-person singular present tense of the verb vera (to be). You need this copula to link subject and adjective, just as in English:
Hafið er kalt. (“The sea is cold.”)
Why is the adjective kalt used here instead of kaldur?
Adjectives in Icelandic inflect for gender, number and case. The dictionary form kaldur is masculine nominative singular. For a neuter noun like haf, the corresponding nominative singular form is kalt (kaldur → kalt).
How do adjectives agree with nouns in Icelandic when used predicatively?
Predicative adjectives (after vera or another linking verb) agree in gender, number and case with the subject:
- Gender: neuter → kalt
- Number: singular → no plural ending
- Case: nominative → no additional suffix
Hence kaldur (m. sg.) becomes kalt (n. sg. nom.) to match hafið.
How would I turn Hafið er kalt into a question “Is the sea cold?”?
Invert the verb and subject: Er hafið kalt?
Can I omit er and just say Hafið kalt?
No. Icelandic requires the linking verb vera in this kind of sentence. Hafið kalt would be ungrammatical.
How do you pronounce ð in hafið?
The letter ð is a voiced dental fricative, like the “th” in English the. So hafið is pronounced [ˈhaːvɪð].
How would I say “The sea was cold” in Icelandic?
Use the past tense of vera, which is var: Hafið var kalt.
