Fundo vs. profundo
The Portuguese words fundo and profundo can both mean deep, but they are used in distinct contexts with nuanced differences in meaning and application.
Fundo
A2Fundo primarily refers to the bottom, base, or end of something, or the concept of depth in a more literal, physical, or spatial sense. It can also describe a deep, low-pitched sound.

No fundo, ele sempre quis ser médico.
(Deep down, he always wanted to be a doctor.)
Profundo
B1Profundo conveys a greater sense of figurative depth, intensity, or abstraction. It is often used to describe emotional depth, intellectual complexity, or something profound in nature.

(She feels a deep sadness.)

Summary
While both fundo and profundo can relate to the idea of deep, fundo is more literal and often denotes the bottom, base, or a tangible depth (e.g., the depth of a well or the bottom of a drawer). On the other hand, profundo typically emphasizes intensity or abstraction, being used in emotional, intellectual, or conceptual contexts (e.g., deep emotions, intellectual depth, or a profound meaning).
