Questions & Answers about He roto el vaso, pero he pegado los pedazos.
Why is it roto? I thought the past participle of romper would end in -ido.
Romper (to break) has an irregular past participle. Instead of the regular -ido ending, it becomes roto. It is one of the common irregulars you just have to memorize, similar to how hacer becomes hecho.
Why does pegar become pegado, but romper does not become rompido?
This sentence perfectly shows the difference between regular and irregular verbs. Pegar is a regular verb, so you just drop the -ar and add -ado to make pegado. Romper is simply a rule-breaker that uses its own special form (roto).
Does vaso mean glass like a window, or glass like a cup?
El vaso specifically means a drinking glass. If you want to talk about glass as a material, like the glass in a window, you use the word el vidrio.
