Etymology: Your word is a Middle English spelling of "light", and all three of its senses come from one Old English ancestor, "lēoht". That word covered brightness and lack of weight, and its verb stem gave the sense of coming down onto something, which survives in modern "alight". The "gh" is a scribal convention. It kept a guttural sound in writing after that sound had mostly disappeared from speech. Behind all of this lies a much older root meaning "light" or "white", which also produced Latin "lux" and Greek "leukos". The shared root explains why brightness and weightlessness sat so close together in English: both describe something that does not weigh down the eye or the body.
