Questions & Answers about Miðinn kostar ekki mikið.

Why does miðinn end with -inn, and how would you say “a ticket” instead?

In Icelandic the definite article is not a separate word but a suffix.

• miðinn = miði (ticket) + -inn (the) = “the ticket.”
  To say “a ticket,” use the indefinite nominative singular miði.

What case and number is miðinn, and how do you know?

miðinn is masculine, nominative singular.

• It’s the subject of the verb kostar (“costs”), so it stands in the nominative.
• The -inn ending signals both definiteness and that it’s singular.

What is the infinitive behind kostar, and what tense and person is kostar?

The infinitive is að kosta (“to cost”).
kostar is the present tense, 3rd person singular form:

• ég kosta (I cost)
• þú kastar (you cost)
• hann/hún/það kostar (he/she/it costs)

Why does ekki (“not”) come after kostar instead of before it?

In Icelandic main clauses, the negation ekki normally follows the finite verb.
Word order here is: Subject – Verb – ekki – Adverbial.
Putting ekki before kostar (e.g. ekki kostar miðinn) would sound ungrammatical.
