Summary
Twice is an inflection of the word Two, that means: two times.
(To get more information about the number Two, see: 2.)
Example
An example of the word "twice" being used in a sentence is....
Joe feel down twice.
This could be equivalently said with the noninflected form (replacing "twice" with "two times") as....
Joe feel down two times.
Once, Twice, Thrice
The word "twice", has two related words: "once" and "thrice".
And they go in the series: Once, Twice, Thrice.
(This means: one time, two times and three times.)
If you want to go past this series, then it goes as: once, twice, thrice, four times, five times, six times, seven times,....
(There are no inflections of this kind, in English, for any other numbers, that I know of.)
