* If "miss" means to fail to hit a target: χάσω (chásō) is the most common translation.
* If "miss" means to feel the absence of someone: μου λείπει (mou leipei - literally "it is missing from me") is a common and natural way to express this. You'd adapt the pronoun (μου - mou) to fit the gender and number of the person you miss. For example: *σε λείπει* (se leipei - "I miss you," informal, singular "you") or *την λείπει* (tin leipei - "he/she misses her").
* If "miss" is a title of address for an unmarried woman (Ms.): κυρία (kyria) is the equivalent, though it's more akin to "Mrs./Ms." and doesn't specifically denote unmarried status like "Miss" does in English. There isn't a direct equivalent that clarifies unmarried status in formal Greek.
* If "miss" is used as a verb meaning to fail to catch or arrive at something in time: χάσω (chásō) or χάσει (chásei - third-person singular) would again be suitable. You might also use a phrase depending on context, such as *δεν πρόλαβα* (den prólava - "I didn't make it in time").
Therefore, there's no single perfect translation. You need to consider the context to choose the most appropriate word or phrase.
