The Origin of Till or Until
Many people believe till is just a short form of until. This is not true.

- Till is the older word, coming from Old English til.
- Until appeared later, formed by adding un- to till.

Till came first. Until came later.
Important note:
- The spelling ’til (with an apostrophe) is informal.
- It suggests a shortened form, but historically till is already complete.
Best practice:
Use till or until, not ’til, in professional writing.
