The word 'fester' means to become worse or more intense over time. It usually describes a problem or a wound that is left untreated and begins to develop infection. For example, a small cut can fester and become an infected wound if it's not cleaned properly. The word can also be used metaphorically to describe a problem or an issue that is left unaddressed and becomes worse over time. In conversation, we might say something like, "If you don't deal with that issue, it will only fester and cause more problems later on."
