Enforce or inforce is a common spelling question because the two words sound almost identical when spoken. However, there is an important difference: enforce is the standard and correct English word, while inforce is generally considered a misspelling when you mean to make sure that a law, rule, agreement, or requirement is followed. The word enforce is commonly used in legal, professional, academic, and everyday English.
For example, police officers enforce laws, schools enforce rules, and organizations enforce policies. The word can also mean to make something effective or ensure that it is carried out.
Although they look/sound similar, they serve completely different purposes. If you’re unsure about enforce or inforce, the safest rule is simple: use enforce when you mean “make people obey or follow a rule, law, or requirement.”
