A common exclamation of sudden mild pain. The spelling varies but this form is very common in informal written and spoken Spanish.
Used in everyday speech to express doubt or disagreement politely. It triggers the subjunctive in the clause that follows, making it a key fixed conversational trigger.
A versatile one-word exclamation. Tone of voice determines meaning: it can signal impatience, signal agreement, or shut down a conversation. Here it appears as an exasperated cutoff.
A very common fixed phrase used to hedge against uncertainty. The acaso on its own means 'by chance' but the full phrase functions as a single unit meaning 'just in case'.
