Usage

What's the difference between twoto, and too? Two is the number equal to one plus one. To is a very common word that performs many different functions, such as expressing direction (I’m driving to the office) or contact (Pin it to the wall), indicating an object or recipient (Give it to me), or setting a range (9 to 5) or limit (These go to 11). Too means also (I’m going, too) or to an excessive degree (too much). The words are used in very different ways: two is a number that can be used as a noun or an adjective, to is most commonly used as a preposition, and too is an adverb. Perhaps the most common mistake involving the three words is using to when it should be too, or vice versa. Remember, if you mean to, don’t use too many o’s!Here’s an example of two, to, and too used correctly in the same sentence. Example: The dealer dealt two twos to me, but it was two twos too few—my opponent had a full house!Want to learn more? Read the full breakdown of the difference between two, to, and too.

Etymology

Origin of two

before 900; Middle English; Old English twā (feminine and neuter; cf. twain); cognate with German zwei; compare Latin duo, Greek dýo

Explanation

Two is a whole number that's greater than one, but less than three. If you found one fuzzy mitten and then your friend gave you another one, you would have two mittens — perfect for your two hands. In a deck of cards, there are four twos — one in each suit. In most games, the two is considered the lowest card. Two can also be used as an adjective to describe anything that numbers one more than one. In cards, if you have a pair of twos, you have two twos. This spelling of two always refers to a number and shouldn't be confused with the homonyms "to" or "too."
