Few words have more than one literal and serviceable meaning, however many metaphorical, derivative, related, or even unrelated, meanings lexicographers may think it worth while to gather from all sorts and conditions of men, with which to bloat their absurd and misleading dictionaries. This actual and serviceable meaning–not always determined by derivation, and seldom by popular usage–is the one affirmed, according to his light, by the author of this little manual of solecisms. Narrow etymons of the mere scholar and loose locutions of the ignorant are alike denied a standing.
