為: sake or benefit. The Japanese noun '為 (ため)' has two primary meanings. The first is 'benefit', referring to something that is advantageous or good for someone or something. For example: for the benefit of the children「子供の為に」(こどものために). The second meaning is 'sake', indicating the purpose or reason behind an action. For example: for the sake of peace「平和の為に」(へいわのために). This word is often used in contexts where the focus is on the purpose or advantage of an action, and it can be paired with particles like 'に' to indicate direction or purpose. It's important to note that '為' can also be written in hiragana as 'ため', and the meaning remains the same.
