Definition of the word thickheaded

The origin of the word "thickheaded" can be traced back to the Old English language, where it was spelled as "brycehed." This word, which is literally translated to mean "brickheaded," originally referred to someone who was particularly sturdy or strong-headed. As the language evolved over time, the word "brickheaded" eventually became "thickheaded" in Middle English. The "thick" part of the word refers to the idea that such a person has an unusually thick skull or head, thus implying a lack of intellectual prowess or quick thinking. Over time, the meaning of "thickheaded" has expanded to also describe someone who is stubbornly ignorant or unwilling to learn new things. In modern usage, the word is often used as a playful insult or teasing remark, indicating that the person in question may have difficulty admitting they are wrong or understanding complex ideas.
