Usage Note: The introduction of the verb intrigue to mean "to arouse the interest or curiosity of" was initially resisted by writers on usage as an unneeded French substitute for available English words such as interest, fascinate, or puzzle. Only 52 percent of the Usage Panel accepted this usage in 1968. Twenty years later, in 1988, 78 percent of the Usage Panel accepted it in the sentence The special-quota idea intrigues some legislators, who have asked a Washington think tank to evaluate it. By the 21st century, the use of intrigue as a verb had become completely unremarkable, and it is now firmly entrenched in the English lexicon.
