Grandiloquent, from the Latin words for “grand” (“grandis”) and “speak” (“landis”), can have a negative connotation of someone coming across as pompous in their speech. But “The New York Times” recently devoted a language column to the category of grandiloquent words (such as “inveigle,” “bamboozle,” and “flummox” — all fanciful synonyms for “trickery”), and described them as “delightful colloquialisms mostly from the 19th century.”
