What does festering mean?
Festering describes the process by which something deteriorates slowly because it has been left untreated. In its literal sense, it refers to a wound or sore that has become infected, producing pus and refusing to heal. Far more common today is its figurative use: resentments, grudges, disputes, and social problems are said to be festering when they intensify quietly over time because no one has addressed them. The word carries unmistakably negative connotations, evoking both physical decay and moral or emotional corruption, and it implies that intervention could have prevented the damage. A manager might ignore a festering conflict between colleagues; a government might overlook a festering crisis in an overlooked region. Derived from the verb 'fester', which entered English in the late medieval period via Old French and ultimately traces back to Latin, the word is vivid and slightly visceral — chosen precisely because it makes abstract neglect feel as unpleasant as an untreated wound.
Becoming infected and filled with pus; or, figuratively, growing worse or more intense through neglect.
"The argument had been festering between them since the holidays."
Almost always used with continuous tenses when figurative, emphasizing ongoing deterioration.
Infected and discharging pus; or, describing a grievance, conflict, or problem that has been neglected and has worsened.
"The report exposed the festering corruption at the heart of the agency."
The process or condition of festering; matter produced by such decay.
"The physician cleaned away the festering from the ulcer."
This nominal sense is comparatively rare and chiefly literary or technical.
As a noun, festering is almost always used as an uncountable mass noun referring to the process or discharge; a plural form is not established in ordinary usage.
"The festering continued despite the antibiotics."
Before it meant anything emotional, 'fester' was purely medical: it traces back through Old French to Latin fistula — the word for an abnormal pipe-like passage in the body.

Etymology of festering
Festering derives from the verb 'fester', which entered English in the late Middle Ages from Anglo-Norman and Old French forms such as 'festrir'. The French verb is generally traced to 'fisse' (pus), ultimately connected to Latin 'fistula', meaning a reed or pipe and later an abnormal channel in the body — making 'fistula' and 'fistulous' its closest English relatives. Originally a strictly medical term for wounds producing pus, it developed its figurative sense of worsening grievances and conflicts in English usage by the early modern period.
