Questions & Answers about Ég á hjálm.
In this sentence, á is not the preposition á (on), but the verb á, which is the present tense form of the verb að eiga (to own, to have).
- að eiga = to own / to have (in the sense of owning or possessing)
- Ég á hjálm = I own / I have a helmet.
So á here is a verb meaning own/have, not the preposition on. It’s like English bank (a financial bank vs. a river bank): same spelling, different function and meaning, distinguished by context.
Present tense singular:
- Ég á = I have / I own
- Þú átt = You (singular) have
- Hann / hún / það á = He / she / it has
Present tense plural:
- Við eigum = We have
- Þið eigið = You (plural) have
- Þeir / þær / þau eiga = They have
So Ég á is 1st person singular present: I have / I own.
