What does instruct mean?
Instruct is a formal verb meaning to tell someone to do something, to teach someone a subject or skill, or to provide authoritative information about how something should be done. It is commonly used in instructions, workplace guidance, education, manuals, and legal or official contexts. Unlike the relatively neutral verb tell, instruct often suggests that the speaker has authority or that the direction is deliberate and systematic. In its educational sense, it can describe the process of imparting knowledge, as in a course that instructs students in grammar. The word can also appear in the phrase “instructed by,” where it identifies the source of a direction. Whether used as a command or a method of teaching, instruct conveys a sense of clarity, authority, and purposeful guidance.

Where does instruct come from?
The English verb instruct comes through Middle English from Old French instruire, ultimately from Latin instruere, meaning “to equip, prepare, or teach.” The Latin word combined the prefix in- and struere, “to build,” giving it the sense of constructing or preparing someone through knowledge or training. Related English words such as instrument, structure, and construction preserve elements of the same Latin root.
