Thesaurize

Thesaurize: verb. To look for something, most probably a word in a thesaurus. This action is very common, although not as common as dictionarizing, nonetheless it is still quite surprising that thesaurizing hasn't become more popular in everyday speech. Unsurprisingly the word was coined by Peter Mark Roget, the creator of the first modern thesaurus, although interestingly he himself never used the word, because he became disillusioned with it.
