Dictionarize

Dictionarize: verb. Although you may think this means to add something to a dictionary, it in fact means to look something up in a dictionary; this word is significantly more popular than thesaurize, but is still used very rarely, something which has for years depressed the Webster family, who's ancestor, Noah Webster, coined the word after having found that in none of the 27 languages he learnt, was there a word to well suit his newest publication.
