Quick Definition
Profound (adjective) means either very great or intense (a profound effect) or showing deep insight and serious meaning (a profound thinker). In both senses the central idea is depth — felt or understood far below the surface.
Example: "The discovery had a profound impact on modern medicine."
What Does Profound Mean?
The word profound comes from the Latin profundus, meaning "deep" (from pro- "forth" + fundus "bottom"). It entered English in the 14th century and originally referred to physical depth before developing its modern figurative meanings.
Today profound has two closely linked senses. The first is intensity: a profound effect, profound change, or a profound sense of loss — something felt very strongly. The second is depth of insight: a profound observation, a profound book, or a profound thinker — ideas that go far beyond the obvious.
Profound is a formal, high-value word common in academic essays, reviews, and speeches. It is neutral in tone: you can feel a profound joy or a profound sorrow. What stays constant is the sense of great depth, whether in impact or in meaning.

Profound carries more weight and is preferred in academic and literary writing.

The context and the noun decide whether the overall meaning is positive or negative.
