Memorial, Monument, Memento, Souvenir, and Memorandum agree in meaning that which puts one in mind or helps one to remember; all but memorandum are especially means of keeping a revered or endeared person, place, etc., in memory. A memorandum is simply a note made in order to prevent the forgetting of something important, especially something which might easily slip from the mind Memento and souvenir differ very slightly, souvenir being a somewhat more elevated word: we give a book or a lock of hair as a memento; we prize a faded flower as a souvenir of a visit to Mount Vernon with friends now separated from us.
