Learn Hardcore Icelandic: Systirin syngur fallega.

Systir is the Icelandic word for “sister.” When you add the suffix -in, you get the definite article attached to the noun: systirin literally means “the sister.” In Icelandic, instead of placing a separate word for “the” before the noun, you usually add -inn/-in/-ið (depending on gender and case) directly to the noun.

What case is systirin in, and how do I recognize it?

Systirin is in the nominative case, which is used for the subject of a sentence. You recognize it by:

Its role: it’s performing the action (“the sister” is singing).
The form: nominative singular feminine definite for systir is systirin.

What is the infinitive form of the verb syngur, and how does this form fit into the present‐tense conjugation?

The infinitive is syngja (“to sing”). In the present indicative it conjugates as follows: ég syng (I sing)
þú syngur (you sing)
hann/hún/það syngur (he/she/it sings)
við syngjum (we sing)
þið syngjið (you all sing)
þeir/þær/þau syngja (they sing)
Here, syngur is the 3rd person singular present form.

Why is there no subject pronoun like hún in “Systirin syngur fallega”?

Icelandic often drops the subject pronoun when the verb ending already shows person and number. In syngur, the ending -ur tells you it’s 3rd person singular. You can add Hún syngur fallega (“She sings beautifully”) for emphasis or clarity, but it’s not required.

What part of speech is fallega, and how is it formed from the adjective?

Fallega is an adverb meaning “beautifully.” It comes from the adjective fallegur (“beautiful”). To form many Icelandic adverbs from adjectives ending in -ur, you drop -ur and add -lega: fallegur → falleg- + -a → fallega

How would I say “A sister sings beautifully” instead of “The sister sings beautifully”?

For an indefinite noun, simply use the bare form without the definite suffix: Systir syngur fallega
This means “A sister sings beautifully.” If you want to stress “one sister,” you can also say: Ein systir syngur fallega
(literally “one sister sings beautifully”).
