What "bottom of the inning" means in baseball

In baseball, an inning is the period during which both teams have a turn to bat and field. Each inning typically consists of a top half and a bottom half. The top of the inning refers to the period when the visiting team is hitting, while the bottom of the inning refers to the period when the home team is at bat. At the bottom of the inning, the home team has the advantage of batting last, meaning they have the opportunity to tie the game or take the lead if they are behind.
