Definition of lay into

The phrase "lay into" is an idiomatic expression that originated in the mid-1800s in the British armed forces. It literally refers to beating or striking someone or an object vigorously, using a cutting or blunt instrument. This action involves laying or placing the instrument into contact with the object being struck. However, over time, the term "lay into" has evolved to denote a figurative meaning, particularly in the context of criticism or verbally attacking someone. In this case, instead of a physical instrument, it refers to a verbal or written assault that is delivered forcefully and aggressively. This use of the phrase began to gain popularity in the late 1800s and has since spread to other English-speaking countries, including the United States. The evolution of the use of "lay into" reflects the increasing importance of communication and the role of language in shaping social and cultural norms. As people became more skilled in communicative abilities, the idea of using verbal language as a weapon to attack others became descriptive. Now, "lay into" is a commonly understood phrase that conveys the act of delivering a harsh, forceful criticism to someone.
