A prefix is a letter or a group of letters attached to the beginning of a word (or word root) that partly indicates its meaning. In addition, any good dictionary will give a word’s etymology. I'm looking for an data structure that supports efficient random prefix matching queries (pattern) over a previously known set of words (dictionary). There are a lot of prefixes in English.
