Keeping social distance: the story of the word “aloof” and a few tidbits
It is amazing how many words like aloof exist in English. Even for “fear” we have two a-formations: afraid, which supplanted the archaic afeard, and aghast. Aback, aboard, ashore, asunder—a small dictionary can be filled with them (but alas and alack do not belong here). The model is productive: consider aflutter and aglitter. One feature unites those words: they cannot be used attributively. Indeed, an asunder man and an astride rider do not exist.
