What Spanish phrase means "time and again" or "sometimes"?

The phrase "a veces" translates directly to "sometimes" in English. It is commonly used in Spanish to indicate that something occurs intermittently or not consistently, hence aligning perfectly with the meaning of "time and again" or "sometimes." When expressing habits or frequencies, "a veces" allows speakers to convey that an action does not happen every time, but rather at irregular intervals.

The other options pertain to specific times. For instance, "a la una" means "at one o'clock," indicating a specific moment. "Y media" translates to "and a half," usually referring to half-past an hour. Likewise, "y cuarto" means "and a quarter," denoting a quarter past the hour. None of these phrases convey the sense of frequency encapsulated in "a veces." Thus, "a veces" stands out as the correct choice for expressing the idea of "time and again" or "sometimes."
