Sentimentality is a term that refers to an overly emotional or nostalgic response to something. Some synonyms for sentimentality include maudlin, mushy, saccharine, sappy, mawkish, and over-sentimental. These words all share the same connotation of being excessively sentimental or emotional. They are often used to describe works of art, films, or music that are designed to elicit an emotional response from the viewer or listener. While sentimentality can be effective in small doses, too much of it can be cloying and irritating. Using synonyms like these can help to convey this sense of overdone emotionality in a more concise and precise way.
