Plain English Meaning

A talk where the speaker shows pictures or diagrams along the way to help the audience follow what is being said.

Full Definition

A method of instruction in which a speaker presents information verbally while using visual aids — such as charts, diagrams, models, slides, or photographs — to support and clarify the spoken material. The visuals are secondary to the talk; they exist to reinforce what the instructor is saying rather than to carry the lesson on their own.

Context Anchor

Seen in aviation instructor training, ground lessons, preflight briefings, and classroom explanations where a topic is easier to understand when it is shown as well as described.

Derivation

From Latin illustrare, meaning 'to light up' or 'make clear.' An illustrated talk literally lights up the words by showing what they refer to.
