I'm told that using count till a hundred is improper grammar. What's the correct preposition?


till is an informal variant of until. Oxford Dictionaries says:

Less formal way of saying until.

They both refer to ending at a particular time or event, not a position. So you could say

Count till you get to 100.

because you get to 100 is an event. But you wouldn't say

Count till 100.

because 100 is a number, not a time or event. In that case you would say

Count to 100.

  • Please cite a reference supporting this notion that till is somehow “informal” when used as a preposition, a conjunction, or an adverb. The OED says only that it is “Characteristically northern in reference to place or purpose (though in ME. occasionally midl. or south.); in reference to time, general Eng. from c 1300, though now often superseded by the compound until.” Even if it is now often superseded, that does not mean it is “informal”, and so I can but wonder why you say that. – tchrist Nov 1 '14 at 5:41

Simply count to.... It is the common usage trend which will not raise any eyebrows.


I was taught to use: 'Count to 10, 20 etc'.

Here is also an example

'Count to' means 'Recite numbers in ascending order'
