## Definition

the branch of philosophy that studies the basic nature of reality. It asks big questions about what exists, what time is, and how the mind and body are connected.

For teachers: the branch of philosophy concerned with the fundamental nature of reality, including the relationship between mind and matter, substance and attribute, and potentiality and actuality.

## Examples

- He spent years studying metaphysics to understand the nature of existence.
- The professor's lecture on metaphysics explored whether time is a physical dimension or merely a human construct.
- While physics provides the empirical laws of the universe, metaphysics seeks to address the underlying ontological questions that science alone cannot resolve.

## Pitfalls

- Not "Metaphysics are a difficult subject." but "Metaphysics is a difficult subject." — Like 'physics' or 'mathematics', this word is singular in construction and requires a singular verb.

## Usage notes

- Treated as a singular noun despite the 's' ending; takes a singular verb.
