What These Prepositions Tell Us

Next to, between, and under each describe where something is in relation to something else. That's it — they answer the question where? by giving a physical position. But each one paints a different picture, and mixing them up (or building them incorrectly) causes confusion fast.

Next to means "at the side of," with the two things close together. Between means "in the middle of two things" (or sometimes more). Under means "lower than and covered or hidden by something above." These are not interchangeable, and each has its own grammar pattern:

• next to + noun → The pharmacy is next to the bank.
• between + noun + and + noun → The pharmacy is between the bank and the post office.
• under + noun → The cat is under the table.

Notice that between almost always needs and to connect the two reference points. This is where many learners slip up.

Worked Examples

✅ My keys are under the newspaper on the kitchen counter. ❌ My keys are below the newspaper on the kitchen counter.

Both under and below can mean "lower than," but when one object physically covers or hides another — the newspaper is lying on top of the keys — under is the natural choice. Below suggests vertical distance without direct contact (a valley below the cliff). For everyday objects resting on top of each other, reach for under.

✅ She sat between Marco and Elena at dinner. ❌ She sat between Marco with Elena at dinner.

The connector must be and. No other word works here — not with, not or, not to. This rule holds whether you're talking about people, places, or abstract things (between hope and fear).

✅ The lamp is next to my bed. ❌ The lamp is next of my bed.

Next to is a fixed two-word preposition. There is no form next of in English. You can substitute beside (one word, same meaning), but next to always keeps its to.

Edge Cases Worth Knowing

Between can refer to more than two things when each item is named individually: The treaty was signed between France, Germany, and Italy. However, if you mean "surrounded by a group" in a general sense, among is usually better: She felt comfortable among her colleagues. At B1–B2 level, a safe rule of thumb: use between when you can list the specific items, among when the group is vague or large.

Under sometimes overlaps with underneath and beneath. For physical position, under and underneath are almost identical — underneath simply adds a little emphasis on being hidden or covered. Beneath can sound more formal or literary. In everyday speech and writing, under is the safest default.

Next to can be replaced by beside with no change in meaning, but besides (with an -s) means "in addition to" — a completely different word. Mixing these two up is a classic spelling-based error that changes your sentence entirely:

✅ He stood beside the door. (= next to the door) ❌ He stood besides the door. (This would mean "in addition to the door," which makes no sense.)

The Mistake That Comes Up Most

B1–B2 learners frequently drop the and from between constructions, especially when translating from languages that use a single word or a different connector. They write things like between Monday to Friday or between the sofa the wall. The fix is mechanical: every time you write between, look for and. If it's missing, add it.

A second common error is using next alone without to: The shop is next the station. This is incomplete. Next on its own is an adjective or adverb meaning "the one after this" (next week). To express position, you need the full phrase next to.

Keep these small structural habits — between … and, next to (two words), under (for contact or covering) — and the prepositions will fall into place naturally.
