What does proviso mean?
A proviso is a condition that must be met before an agreement, grant, or statement can take full effect. The word frequently appears in legal and formal contexts, as in “subject to the proviso that,” where it introduces a qualification designed to protect the parties or limit the scope of an arrangement. A proviso is more specific than a general condition because it normally qualifies an otherwise formal promise or entitlement. For example, a contract may promise payment only on the proviso that the work is completed by an agreed date. In everyday discussion, the word can also refer more broadly to any important reservation, although it sounds noticeably more formal than “condition” or “catch.” Its usefulness lies in clearly identifying an exception or prerequisite without requiring a long, separate statement.
nounA condition or qualification attached to a statement, agreement, or grant, especially one that must be satisfied for it to take effect.
- A condition or qualification that limits or qualifies an agreement, statement, or grant.
- A qualifying clause in a contract or other legal document.
"The grant is subject to the proviso that the work must be completed within six months."
"The scholarship is renewable, with the proviso that the student must maintain satisfactory academic results."
"The committee accepted the proposal subject to the proviso that further funding would need to be secured."
The plural is used when referring to several conditions or qualifying clauses.
"The contract contains several provisos concerning deadlines, payment, and termination."
Borrowed from a Latin word meaning “provided,” proviso became the legal world’s concise way of saying “yes, but only if this condition is met.”

Where does proviso come from?
The word comes from Latin provisum, the neuter past participle of providere, meaning “provided” or “supplied.” It entered English in the early 16th century, initially in legal and financial contexts. The same Latin root produced related English words such as provide, provision, provisional, and provident.
