Irish doesn’t technically have the verb “to have”, so what you’re actually saying is “there is a sandwich to me” (or at me, or with me – basically insert a preposition there). agam is the preposition ag + the first person pronoun -m, so that’s the “to me”, and tá is “there is”. But yeah, the word order on eating etc can be confusing. I don’t have a way of explaining that one, although I’m sure there’s a very simple way of clarifying it if you actually understand it.
Basically the verb is still first in “have” because the verb is actually “there is” (tá) and it’s at the beginning like the others. The bit at the end isn’t a verb, it’s tricking you.
Thank you for your comment @trans-cuchulainn! It was actually really confusing me but this cleared it up really nicely. Thank you!
