These verbs mean to make the nature or meaning of something understandable. Explain is the most widely applicable: The professor used a diagram to explain the theory of continental drift. The manual explained how the new software worked. To elucidate is to throw light on something complex: "Man's whole life and environment have been laid open and elucidated" (Thomas Carlyle).

To interpret is to reveal the underlying meaning of something by the application of special knowledge or insight: "A radiologist can interpret images made in Saudi Arabia and beamed to Boston, sending back a diagnosis within hours" (Richard Saltus).
Construe involves putting a particular construction or interpretation on something: "I take the official oath today ... with no purpose to construe the Constitution or laws by any hypercritical rules" (Abraham Lincoln).
