Definition of the word substantiate

The word "substantiate" originates from the Latin word "substare," which translates to "stand under." In Middle English, the word was spelled as "substainiien" and meant "to support, maintain, or establish." Over time, the meaning of the word evolved, and in the 14th century, it began to refer to providing evidence or proof to support an argument, claim, or statement. This meaning of the word can be seen in its use in legal contexts, as in the phrase "to substantiate a claim in court." Another meanings that emerged was "to provide something necessary or essential," which is closely related to its original meaning of "standing under" something. For example, in the expression "substantial breakfast," the word refers to a meal that is filling and provides the necessary sustenance to start the day. Overall, the word "substantiate" derives from its Latin origins, but its meaning has shifted and evolved over time to encompass both supportive arguments and essential provisions.
