Elucidate

Simple meaning

Elucidate means to make something clear by explaining it carefully — shedding light on what was obscure, complex, or poorly understood.

Detailed meaning

Elucidate comes from the Latin elucidare — to make clear, to bring into the light (lux = light). When you elucidate something, you illuminate it — you bring clarity to what was obscure.

It is a formal word — more at home in academic writing, professional analysis, and careful speech than in everyday casual conversation.

Elucidate is stronger than explain. To explain is to give information. To elucidate is to genuinely clarify — to make the listener or reader understand something they didn't, or couldn't, understand before.

Common uses:

• "Could you elucidate your reasoning?" — please explain more clearly.
• "The data elucidates a pattern that wasn't visible before." — makes it clear.
• "She was asked to elucidate her methodology." — explain it in a way that makes it understandable.

Where to use it

It works well in:

• Formal requests for clarity — "Can you elucidate your position on..."
• Academic and research writing — "this study helps elucidate..."
• Professional presentations — "I'd like to elucidate the three key assumptions..."

Where not to use it

Elucidate is formal. In casual conversation, just say explain, clarify, or make clear.
