When do I use "Below" and when do I use "Under"?

"Below" = lower level (temperature, budget, position without contact). "Under" = beneath with covering, hierarchy, or physical contact.

What is the most common mistake with "Below" and "Under"?

"The cat is below the bed" sounds like the cat is in the apartment downstairs. For something physically beneath with covering or contact, use "under". "Below" is for abstract levels or position without direct contact.

How do I remember the difference between "Below" and "Under"?

"Below" is the opposite of "above" (level, no direct contact). "Under" is the opposite of "over" (covering, hierarchy, physical contact).

Did you know?

"Under" has enormous idiomatic richness: "under pressure", "under the weather" (feeling ill), "under construction", "under arrest", "undercover", "underage". "Below" rarely forms fixed idioms. English strongly prefers "under" for power relations, states, and control relationships. This reflects the original Old English sense of "under" as both spatial and hierarchical.
