Difference Between Hollow and Shallow

Key Differences

Hollow often describes something that has an empty space inside. This can be either because it was designed that way or because it has been worn out or decayed over time. Shallow, on the other hand, is typically used to describe something that does not have much depth.
In terms of physical structures, a hollow log would be a log with a void or cavity inside. A shallow pond would mean that the water doesn’t go very deep, possibly allowing one to see the bottom or walk across with ease.
Hollow can also describe feelings. For example, a "hollow victory" implies a win that feels empty or unsatisfying. In contrast, shallow can describe a person's personality or character, indicating they lack depth or substance.
When it comes to sounds, a hollow sound might echo, like the noise made when knocking on a hollow door. A shallow breath, however, is one that is not deep, potentially indicating difficulty breathing or a light sleep.
While both terms describe a lack or absence of something, hollow usually pertains to a void within a structure or feeling, while shallow primarily describes a lack of depth or substance.
