Prone means likely to do or suffer something, and it also describes lying face downwards. To use prone in a sentence, pair it with to and a noun or an -ing verb: “Cheap laptops are prone to overheating.” The adjective most often follows be, seem or become, and the physical sense appears after lie or fall.

- The dominant pattern is prone to plus a noun or an -ing verb, as in prone to error.

What does prone mean?
Prone is an adjective meaning likely to do, suffer or show something, usually something unwanted, and a separate sense means lying face downwards. The Cambridge entry for prone records both, and the likelihood sense nearly always travels with to: crops prone to frost, a knee prone to injury. Where the risk is legal or the outcome merely possible, liable is often the more exact word.
| Sense | Plain meaning | Example sentence |
|---|---|---|
| Likely to suffer | Exposed to something unwanted | Damp cellars are prone to mould. |
| Likely to do | Having a tendency to act in a certain way | He is prone to exaggerate. |
| Lying face down | Resting flat with the front downward | She lay prone on the mat. |
One limitation is worth stating plainly. Prone is not a synonym for certain or destined, and it usually points at a risk. A neutral habit such as reading is better written tends to read, because prone would imply something to worry about.

| be + prone to + noun | The road is prone to flooding. | States a standing risk. |
| lie or fall + prone | The climber lay prone on the ledge. | Uses the physical sense. |
| accident-prone | an accident-prone cyclist | A compound for someone who often has mishaps. |

Prone vs liable
Prone and liable overlap in the sense of likelihood, and they part company over duty and law. Prone also sits near susceptible, which stresses sensitivity rather than habit.
| Attribute | prone | liable |
|---|---|---|
| Core meaning | Tending towards something, often a risk | Likely to happen, or legally responsible |
| Typical pattern | prone to + noun or -ing | liable to + verb; liable for + noun |
| Focus | A characteristic tendency | A chance outcome or a legal duty |
| Typical subject | People, things and places | People, companies and decisions |
| Register | Neutral to formal | Formal, often legal |
Verdict: use prone for a tendency, liable to for a possible outcome, and liable for when the question is legal responsibility.
Word forms and grammar of prone
Prone has a small family, and its physical sense gives two useful near neighbours. The table lists the forms and the contrasts.
| Form | Part of speech | Example |
|---|---|---|
| prone | adjective | a prone sleeper |
| proneness | noun | His proneness to worry tired him. |
| prone, posture sense | adjective | The swimmer floated prone. |
| supine | adjective — opposite posture | He lay supine, staring at the ceiling. |
| prostrate | adjective — related posture | The runner lay prostrate at the finish. |
The posture sense is easy to reverse: prostrate implies weakness or defeat, while inclined describes a gentle preference rather than a flat position.

Answers

- She is prone to forgetting her keys — prone to takes an -ing form here, not a bare verb.
- Model answer: The garden path is prone to flooding after heavy rain.

The bottom line
Use prone in a sentence when something is likely to suffer a particular problem, and remember that the word usually points at a risk rather than a neutral habit. The two nuances that decide most sentences are these: the fixed pair is prone to followed by a noun or an -ing form, and a separate sense means lying face downwards. For a plain statement of likelihood, likely is the simpler choice.
Frequently asked questions about prone
Is it prone to do or prone to doing?
Both appear, but prone to doing or prone to plus a noun is the safer choice in formal writing. He is prone to forget is understood, yet he is prone to forgetting and his proneness to error read more naturally. When in doubt, turn the verb into an -ing form or a noun.
What does lying prone mean?
Lying prone means lying face downwards, flat on the front of the body. A swimmer, a sniper or a child studying ants can all be described as prone. The opposite position is supine, which means lying face up, and the two words are easy to mix up because neither is used in everyday speech.
Can prone be used without to?
Yes, in the physical sense. A person can lie prone, fall prone or be found prone without any to. The likelihood sense, however, nearly always needs to, because prone alone cannot name what a thing tends to suffer. That is why the fixed pair prone to appears so often.
Is prone the same as likely?
Not quite. Likely states a plain chance, while prone adds the idea of a standing tendency towards something unwanted. A player prone to injury has a history of it, whereas a player likely to score is merely expected to. Prone also carries more judgement than likely.
