Questions & Answers about Poso el collar i l'arnès a la mascota.
Poso comes from the verb posar, which means to put, to place, or in this kind of context, to put on.
So Poso el collar i l'arnès a la mascota means that I put / I’m putting the collar and the harness on the pet.
Catalan often leaves out subject pronouns when they are clear from the verb ending.
Here, poso already tells you the subject is I, so jo is unnecessary. You could say Jo poso el collar i l'arnès a la mascota, but it would usually add emphasis, as in I’m the one putting them on.
Because the masculine singular article el becomes l' before a word that starts with a vowel or silent h.
So:
- el collar
- l'arnès
This is just the normal apostrophe rule in Catalan.
