IPA: /ˈdaɪəɡræf/
KK: /ˈdaɪəˌgræf/
A tool used for drawing that combines a protractor and a scale, helping to create accurate measurements and angles.
The architect used a diagraph to ensure the angles of the building were precise.
Diagraph → It is formed from "dia-" (meaning through or across) and "grapho" (meaning to write or draw). The word refers to a method of writing or drawing that involves going through or across something, often used in the context of diagrams or illustrations.
Think of 'writing' ('grapho') that goes 'through' or 'across' ('dia-') something — that's what a diagraph does.
