“Nebbish” is an informal term often used to describe a person who is timid, ineffectual, or submissive. The word suggests a lack of confidence and a tendency to be overlooked or ignored. It can also imply a certain level of awkwardness or ineptitude in social situations. The term is often associated with characters in literature and film who are portrayed as weak or overly passive, making it a useful descriptor for someone who might be perceived as lacking assertiveness or presence. The origin of the word is believed to come from Yiddish, reflecting its use in American English, particularly in the context of Jewish culture.
