each month M-W posts the Top Twenty lookups at their online site for the previous month; for April aloof placed 15th.

Here is the strange case of aloof. It ranked in the 30s and 40s during December and January, was in the 20s in February and March, and moved into the Top Twenty last month. Frankly, we don't know why. It tends to be looked up most frequently on Mondays; April 24th was its biggest single day; and it's still going strong in May.
