usage note For memento

Memento is sometimes spelled momento, perhaps by association with moment. The word is actually related to remember. One of its earliest meanings was “something that serves to warn.” The meaning “souvenir” is a recent development: The stone animal carvings are mementos of our trip to Victoria. Momento is considered by many to be a misspelling, but it occurs so frequently in edited writing that some regard it as a variant spelling rather than an error.
