The word "taught" is the past tense of the verb "teach," which means to impart knowledge or skills to someone through instruction. It is often used to describe a process where one person, typically a teacher or mentor, helps another person understand or learn something new.
The word "taught" comes from Old English "tæcan," which is derived from the Proto-Germanic "taikōną," meaning "to show, point out, or teach." The root can be traced back further to Proto-Indo-European "deik-" meaning "to show."
