The Greek word "για" translates to "for" in English. It is commonly used to indicate purpose, reason, or direction. For example, one might say "για σένα" meaning "for you," which shows intention or benefit directed towards someone. In addition to its use in expressing purpose, "για" can also indicate a specific time or place. For instance, "για αύριο" means "for tomorrow," suggesting a deadline or timeframe. This versatility makes "για" an essential preposition in the Greek language, useful in various contexts and conversations.
