What does enforce mean?
To enforce is to make sure that a law, rule, agreement, or standard is actually followed — usually by an authority with the power to punish non-compliance. Governments enforce statutes, courts enforce contracts, schools enforce dress codes, and employers enforce workplace policies. The verb carries an inherent sense of power asymmetry: someone in a position of authority applies pressure, whether through inspection, penalty, or legal action, to secure obedience. A second, somewhat rarer sense means to impose something by force, as in enforcing one's will on others. The word is firmly rooted in formal and institutional language, appearing constantly in legal writing, news reporting, and public administration. Its derivatives — enforcement, enforceable, enforcer — show how central the concept is to modern governance: a law on the books has little practical effect until it is enforced, which is why debates about enforcement often matter as much as debates about the rules themselves. The word ultimately derives from Latin fortis, meaning strong.
verbTo compel observance of or compliance with a law, rule, or obligation, typically by authority or the threat of penalty. More broadly, to bring about or impose something by force.
- To ensure observance of or obedience to (a law, rule, or obligation), especially through official authority and penalties.
- To impose or bring about something by force or compulsion.
"The city began enforcing its new parking regulations last month."
"Police officers were deployed to enforce the curfew across the city centre."
"The contract terms are legally binding and will be enforced if breached."
The "force" in "enforce" is literal — the word comes straight from Latin fortis, meaning "strong," so every law you obey is backed by an ancient word for strength.

Etymology of enforce
Enforce entered English in the late Middle Ages from Anglo-Norman and Old French enforcier, meaning to strengthen or apply force, which itself derives from Latin fortis, meaning strong — the same root that gives us force, effort, reinforce, and fortify. Its earliest English senses centred on strengthening or exerting force, but by the sixteenth century the dominant meaning had shifted to compelling obedience to rules or laws. The noun enforcement followed soon after, cementing the word's place in legal and administrative vocabulary.

How enforce is actually used
Enforce is largely neutral-to-formal in register and appears most often in legal, governmental, and institutional contexts. It typically takes a rule, law, agreement, or policy as its direct object; it is less commonly used with people as the object. The passive form is frequent, reflecting the top-down nature of enforcement.
