    In a nutshell, they can be used interchangeably in most situations, with the obvious exception of fixed phrases such as "Till death do us part". Some people will object to "till" (as being too informal or whatever), but only for entirely made-up reasons (such as that "till" is a careless abbreviation of "until" or something, which is simply wrong; "till" is actually the older of the two words, and "until" was derived from it rather than the other way round). – RegDwigнt Dec 18 '10 at 8:38
  • @RegDwigнt cool, learned something new. I was, until now, one of those that that till was just a truncated until. – Kevin Oct 25 '16 at 23:37
  • I guess they are historically related like to and unto? – Anton Sherwood Apr 20 at 5:17

@RegDwight is correct in every particular. Till is indeed older and the two can be used pretty much interchangeably.

There is really only one usage I can think of where you would not use till: in setting up a negative conditional.

Until my landlord fixes the plumbing, I am not going to pay the rent.

I am not going to pay the rent until my landlord fixes the plumbing.

Here it would sound strange to use till, and I'm not really sure why. Perhaps it is the negative.

One more thing. Sometimes you will see people spell till as a contraction of until: that is, as 'til. This is simply wrong, and not seen outside of old poetry and modern greeting cards aiming for a "poetic" tone. Anywhere you see 'til being used, till would be the correct word.

    +1 for "RegDwight is correct in every particular" (^_^). Seriously though, +1 for the rest as well. (See e.g. Wiktionary marking "'til " as nonstandard, saying "Those unaware of ['till' being older than 'until'] sometimes assume that till is a short form of until and hence spell it as 'til. This word is nonstandard but in widespread use.") – RegDwigнt Dec 18 '10 at 14:10

    I don't think it's the negative, but simply flow - note that "It ain't over till the fat lady sings" is fine. However, "rent till" is harder to parse than "rent until", and also harder to say due to the double 't'. – Mark Dec 18 '10 at 14:55

    I don't find "till" strange in that sentence. Am I the only one? – Kosmonaut Dec 18 '10 at 15:35

    @Kosmonaut: The second example would sound less strange using till but I really can't wrap my ear around that usage in the first. Perhaps it's a regional thing. – Robusto Dec 18 '10 at 16:30

    @Robusto - Til was noted in ME and has been in continuous since then as well. 2010 May, Parker, James, “Revenge of the Wimps”, The Atlantic Monthly, volume 305, number 4, page 38:  EVEN IF YOU MAKE ME WRITE IN THIS EVERY DAY TIL THEY LET ME OUT OF HERE ... – AnWulf Jun 3 '12 at 15:04

Usage

According to the usage notes from the entry for till in dictionary.com, until and till are interchangeable:

Till and until are both old in the language and are interchangeable as both prepositions and conjunctions:

It rained till (or until ) nearly midnight.

The savannah remained brown and lifeless until (or till ) the rains began.

Till is not a shortened form of until and is not spelled 'till. 'Til is usually considered a spelling error, though widely used in advertising: Open 'til ten.

Etymology

According to the entries for till and until in the Online Etymology Dictionary, until would have derived from till:

until = und + till, where und was an Old English word meaning "as far as, up to".

till O.E. til (Northumbrian), from O.N. til from P.Gmc. *tilan (..) A common preposition in Scandinavian, probably originally the accusative case of a noun now lost except for Icelandic tili (..) the noun used to express aim, direction, purpose.

until c.1200, from O.N. und "as far as, up to" (related to O.E. end; see end) + till "until, up to" (see till). Originally also used of persons and places. Cf. Swed. intill, Dan. indtil. The Mod.Ger. equivalent, bis (O.H.G. biaz), is a similar compound, of O.H.G. bi "by, at, to" and zu "to

  • Wow so both till and until were borrowings from Old Norse into Old English. I wonder what was used before the borrowing? – hippietrail Mar 30 '18 at 0:46

It's been suggested that there's a difference in aspect: till is used with continuous actions, while until is used for perfective. However, this is not supported by any references or general usage, and seems to be an independent analysis.

The only difference is that until has no homophones. I'd suggest using until whenever there's a risk of confusion or difficulty in pronunciation, and only use till where it's suitable for the flow. Till, being older and ambiguous is often used poetically ("till death do us part") which affects the tone of the sentence. I therefore generally avoid till in technical writing.

Finally - as has already been mentioned - 'til is a hypercorrection, and is best avoided.

  • This link works for me and the article makes excellent sense to me. I will copy two examples from that article here: a) He works till 5 p.m. every day. Right. (Explanation: He works the whole day/ from the reporting time to 5 p.m. and not after that.) b) He works until 5 p.m. every day. (Grammatically wrong and makes no sense!) This sentence would work, rather: "He works until it is 5 p.m. every day." (Explanation: He works till the time its 5 p.m. Here, there is no reference of the time-period before 5p.m.) – HongboZhu Feb 25 at 10:03
  • BTW, the linked article's conclusion also totally agrees with the example given in @Robusto's answer. – HongboZhu Feb 25 at 10:13
  • I see nothing wrong with the sentence "He works until 5pm every day", although it might be more idiomatic might be just to say "until 5". Google for phrases like this, you'll find they're standard usage. – Mark Feb 26 at 11:45
