What does cutoff mean?
A cutoff is a clearly defined limit or stopping point — most often a date, time, score, or quantity beyond which something is no longer accepted, counted, or allowed. In everyday administration it appears constantly: universities set enrollment cutoffs, tax offices publish filing cutoff dates, and competitions announce submission deadlines as cutoffs. In engineering and technical contexts, cutoff also refers to a physical mechanism that interrupts flow or power, such as a fuel shutoff valve or a circuit breaker acting as a cutoff for electrical current. The noun is typically neutral and functional in tone, carrying no strong connotation, though missing a cutoff can carry real consequences. It is usually written as one word, distinguishing it from the verb phrase 'cut off'. Because so much modern life is organized around thresholds and deadlines, cutoff is a practical, widely applicable term worth knowing precisely.
A limit, deadline, or boundary beyond which something is not accepted, counted, or allowed.
"The cutoff for entries is 5 p.m. on Thursday."
Often used attributively before another noun, as in 'cutoff date' or 'cutoff time'.
A device or control that stops the flow or operation of something, such as fuel or electric current.
"She reached for the emergency cutoff when the machine began to overheat."
Regular plural; used both for multiple limits or deadlines and for multiple stop devices.
"The agency publishes its income cutoffs each January."
A single word that can mean both a deadline you race against and a valve that shuts everything down.

Etymology of cutoff
Cutoff is formed within English from the verb 'cut' combined with 'off', following the productive pattern by which verb-plus-particle combinations become single-word nouns (as with 'takeover' and 'makeup'). The base verb 'cut' has been part of English since the medieval period, appearing by the late Middle Ages, though its deeper origins are debated — possibly influenced by Old North French or Old Norse. As a compound noun, cutoff developed alongside industrial and administrative usage, becoming especially common in the nineteenth and twentieth centuries as formalized deadlines and mechanical stop-devices proliferated.
How cutoff is actually used
Common in administrative, financial, and technical contexts; often used attributively (e.g. 'the cutoff date'). The related verb phrase is 'cut off', written as two words.
