The process by which something is reloaded.
"The automatic reloading of the weapon continued until the magazine was empty."
In plain English: A reload is an extra round of ammunition that you put into your gun when it runs out so you can keep shooting.
"The game ended when his ammo was completely reloaded and he had to start from scratch."
To load (something) again
"After running out of bullets, he had to reload his revolver before continuing the chase."
Usage: Use reload as the verb to describe loading data, ammunition, or software content into its original state after it has been used. This term specifically implies refreshing existing material rather than introducing entirely new information for the first time.
The word reload comes from combining the prefix re- with load. It originally meant to put a fresh supply of ammunition into a weapon again after it had been emptied.
