✅ A job is a regular activity performed in exchange for payment (I’ve had several jobs in the restaurant industry).
✅ An occupation is a person's principal work and involves a level of specialization (His occupation as a writer allowed him to work from home).
✅ Both words describe what a person does to earn money.
✅ Occupation can imply a career or profession, while job often refers to a specific role or task (Eric's occupation is plumbing; last week he had a tough job where he had to unclog a nasty sink).

✅ To appear means to become visible or come into sight (Mountains slowly appeared in the distance as we drove).
✅ Materialize refers to something becoming real or actual, often suddenly or unexpectedly (The ghost materialized out of thin air, startling everyone in the room).
✅ Both terms are used to describe something coming into view or existence.
✅ While appear often applies to visual perception and is more commonly used, materialize is more dramatic, often implying something almost magical (The rabbit didn’t just appear from the hat — it materialized, stunning the audience).

✅ A hospital is a large medical facility where people receive treatment for illnesses and injuries (He was admitted to the hospital after the accident).

✅ An infirmary is a smaller medical facility, often within an institution or school (The infirmary treated minor injuries and illnesses).

✅ Both terms refer to places where medical care is provided.

✅ A hospital is used for large, comprehensive medical centers, while infirmary is typically used for smaller, often institutional facilities such as military bases, universities, monasteries, and prisons.
