Definition of lousy

The origin of the word "lousy" can be traced back to the Middle English word "lous," which referred to a type of parasitic insect called a louse. These insects were commonly found on people's bodies and clothing, especially in times of poor hygiene. As the term "lousy" began to be used in Old English, it initially conveyed a meaning related to the presence of lice. Its earliest recorded use dates back to the 15th century in the form of "louseye," meaning "infested with lice." Over time, the meaning of the word evolved to encompass more general connotations of worthlessness, inferiority, and unpleasantness. By the 17th century, the definition of "lousy" had expanded to include any object or condition that was unsatisfactory, worthless, or dirty. In modern English, the word "lousy" is commonly used to describe something that is substandard, imperfect, or deficient in some way. Many slang words and expressions have also incorporated the term, such as "lousy buck" (meaning a poor-quality dollar) and "lousy deal" (meaning an unfair transaction). Thus, the origins of the word "lousy" serve as a reminder of the importance of hygiene and personal cleanliness as well as the evolution of language over time.
