What is the correct Spanish phrase for "and a half"?

The correct Spanish phrase for "and a half" is "y media." This phrase is commonly used to refer to times when the hour is halfway through, such as 1:30, which can be expressed as "es la una y media." The term "media" literally means "half," making it a direct translation for indicating a time that is thirty minutes past the hour.

In contrast, "y cuarto" translates to "and a quarter," referring to fifteen minutes past the hour, which does not convey the concept of being halfway. "A la una" means "at one o'clock," and is more about the specific hour than indicating a duration of time. "El verano" refers to "the summer," which is unrelated to timekeeping. Therefore, "y media" stands out as the correct phrase to use when expressing "and a half" in the context of time.
