Definition of the word like

The word "like" has a rich history, dating back to Old English. The Proto-Germanic root *likiz, meaning "form" or "shape," is believed to be the source of the modern English word "like." This root also gave rise to the Old English word "līc," which meant "like" or "similar." In Middle English, around the 11th to 15th centuries, "like" began to take on a new meaning, conveying a sense of agreement or approximation. For example, "I like the book" implied a fondness or approval. This sense of approval or agreement is still present in modern English, as in "I like your idea." In the 20th century, the word "like" took on a new role as a filler word or hesitator in casual speech, particularly among young people. This usage is often referred to as "serial 'like,'" where the word is used repeatedly to punctuate speech or express tentative agreement.
