The English language has many words that contain a negative prefix, and for the most part these prefixes give us an easy way to parse the meaning of the prefix-less form: those who disagree fail to agree; to be unaware is to not be aware; and an amoral person is not concerned about the morality of their behavior.
But not every prefix that looks like a negative prefix is a negative prefix. While aloof is indeed formed from a prefix a- and a word loof, the prefix is not the negating one found in amoral, but is instead the prefix a- found in abed, aloud, and afire. Loof is a variant of luff, which in Middle English referred to the side of a ship that faces the wind; the earliest meaning of aloof was “to windward.” Soon after the word entered English it began to be used to mean “at a distance,” and soon after that, it took on the meaning of “physically or emotionally removed.”
