(Used with object) to make lucide or clear, especially by explanation or analysis; (used without object) to give a clarifying explanation.

The word “elucidate” comes from the Latin term "lucidus" which means " lucid." Lucidus, in turn, comes from the verb "lucēre," meaning "to shine." So elucidating can be thought of as the figurative equivalent of shining a light on something to make it easier to see.
