The word "taught" is the past tense of the verb "teach." It means to impart knowledge or skills to someone through instruction, guidance, or experience. When you teach someone, you help them learn about a particular subject or how to perform a specific task.
The word "taught" comes from the Old English word "tĒ£can," which means "to show, demonstrate, or instruct." Over time, it evolved into the modern form "teach," with "taught" serving as its past participle and simple past form.
