The phrase "at the same time" refers to two or more events or actions occurring simultaneously. It indicates that these things are happening concurrently, without delays or interruptions between them.
The phrase "at the same time" originated from Middle English and can be broken down into its component parts. "At" comes from Old English "æt," meaning "in the position of." "Same" comes from the Old English "same," meaning "even, uniform." "Time" derives from the Old English "tīma," which means a period or duration. The phrase as a whole emphasizes the occurrence of multiple events within the same time frame.
