What does lecture mean?
A lecture is a formal talk given to an audience, most often by a teacher, professor, or guest speaker. It may inform, persuade, explain, or entertain, and it is commonly associated with education, public speaking, and academic presentations. The verb “lecture” can mean either to deliver such a talk or to reprimand someone forcefully and at length. In the second sense, the word often suggests an unwanted but earnest moral lesson: someone is being told, emphatically, what they ought to do differently. “Lecture” comes ultimately from Latin, where its source meant “a reading” or “something read aloud.” Its educational sense developed from the practice of reading authoritative texts to students, while its modern disciplinary sense reflects the idea of instructing or admonishing someone.
A talk given to an audience, especially by a teacher or lecturer; also, a long talk intended to warn, advise, or reprimand.
"The lecture on climate change was attended by several hundred students."
The disciplinary sense, as in “give someone a lecture,” is often mildly disapproving.
To teach or address an audience in a formal talk, or to reprimand someone at length.
"He lectured the class on the importance of careful sources."
When used in the sense of reprimanding, this verb is typically transitive and takes a person as its object.
The plural is used for separate talks or presentations and for instances of reprimanding someone.
"She gave several lectures on the history of medicine."
From the Latin word for reading, “lecture” originally referred to a text that had been read aloud before an audience.

Where does lecture come from?
The word comes through Middle English from Latin lectūra, meaning “a reading” or “something read aloud.” Latin lectūra was derived from legere, “to read” or “to gather,” a root also represented in English words such as legible and lectern. The original sense referred to the reading of a text to an audience; the educational and reprimanding senses developed from the idea of formal instruction and admonition.
