Definition of boost

The word "boost" has its roots in Old Norse. In the 14th century, the word "bst" or "bost" referred to a violent or sudden movement, such as a kick or a push. This sense of sudden and energetic movement was later adopted into Middle English as "boost" or "boost". In the 16th century, the word "boost" took on a new meaning, referring to a sudden and considerable increase or rise in something, such as a boost in morale or a boost in energy. This sense of the word is thought to have been influenced by the idea of something being "boosted up" or lifted up by a sudden force or energy. Today, the word "boost" is widely used in a variety of contexts, including technology, sports, and everyday language, often referring to a sudden and significant improvement or increase in something.
