Questions & Answers about Ég á átta penna.

Why does this sentence use the verb á (from eiga) instead of hafa to say “have”?

In Icelandic, eiga (present: á) is the normal verb for expressing ownership or possession.

• hafa is used as an auxiliary verb (“have done something”) or for more abstract senses of “have” (e.g. “to hold inside,” or “to have to” when paired with að).
• To say “I have pens” in the sense “I own pens,” you always use ég á penna, not ég hef penna.

Why is the pronoun ég necessary here? Can it be dropped?

The form á is formally identical for both 1st person singular (“I own”) and 3rd person singular (“he/she/it owns”). Because of that ambiguity, Icelandic speakers normally include ég (“I”) to make clear who the subject is.

• Unlike some other verbs whose endings differ for 1st vs. 3rd person, á does not, so the pronoun stays.

Why is the noun penni in the form penna and not penni, penna, or penna with a different case?

penni (“pen”) is a masculine i-stem noun. Its principal forms are:
• Singular: N penni, A penna, D penna, G penna
• Plural: N penna, A penna, D pennum, G penna

In Ég á átta penna the noun is the direct object of á, so it must be in the accusative. The accusative plural of penni is penna. That same form also appears as genitive singular, nominative plural and genitive plural, which can be confusing—here it’s the plural accusative.

The number átta doesn’t change. Do Icelandic numbers inflect for gender or case?

Numbers 5–9 (fimm, sex, sjö, átta, níu) are indeclinable in Icelandic. They stay the same in every gender and case.
By contrast, numbers 1–4 do inflect for gender and case (e.g. einn, ein, eitt; tveir, tvær, tvö; þrír, þrjár, þrjú; fjórir, fjórar, fjögur).

I’ve heard that numbers 2–9 usually put the noun into the genitive singular. Why isn’t penna in the genitive here?

There is indeed a general rule that when a noun is modified by a standalone number 2–9, it takes the genitive singular. However, if that entire noun phrase is also the object of a verb or governed by a preposition, the case required by the verb/preposition takes precedence.

• Here, á requires the accusative, so penni goes to its accusative plural, which by coincidence looks exactly like the genitive singular form penna.

Could I rearrange the words and say Átta penna á ég or Átta á ég penna?

Icelandic follows the V2 rule: the finite verb must come in second position.

• Átta penna á ég is grammatically fine for emphasis on “eight pens” because you’ve fronted the object (“Átta penna”), and the verb á is still second, followed by ég.
• Átta á ég penna would put two constituents (“Átta” then á) in the first two slots, leaving ég penna awkwardly in third and fourth—this breaks V2.
  The normal neutral order is Ég (1) á (2) átta penna (3+).

How can I tell that á in this sentence is a verb and not the preposition á (“on/at/to”)?

Two main cues:

1. Syntactic context: It appears with a subject (ég) and takes a direct object (penna). Prepositions never take subjects.
2. Morphology: As a verb, á is finite (present tense of eiga) and sits in V2 position. As a preposition, it would govern a noun directly (e.g. á borðið “on the table”) but wouldn’t allow a subject pronoun to precede it as part of the same clause.

Why is there no article before penna? Where are “a” or “the” in Icelandic?

Icelandic does not have a separate word for an indefinite article (“a/an”).

• Indefiniteness is just the unmarked form. You say penna for “pens” or “(some) pens.”
• To express “one pen” specifically you can use the numeral einn/eina/eitt.
• The definite article is a suffix on the noun: penni → penninn (“the pen”).
  In our sentence we have a bare numeral + noun, so there is no article at all.
