it's

The thing is

It's is the contraction of "it is" or "it has": It's raining, It's been a long day.

The apostrophe marks the missing letters.

Writers frequently confuse it's with the possessive its, which has no apostrophe—a peculiarity of English where the possessive form breaks the usual apostrophe rule.
