precipitation
B2Academic, Technical, Formal, Everyday (for weather)
Definition
Meaning
Water in liquid or solid form that falls from the atmosphere to the Earth's surface (e.g., rain, snow, hail).
The process of a substance being separated from a solution as a solid; a hasty, impulsive, or abrupt action.
Linguistics
Semantic Notes
In chemistry, the process is called precipitation. The metaphorical 'hasty action' sense is more formal and less common.
Dialectal Variation
British vs American Usage
Differences
No significant difference in core meaning. In weather forecasts, both use 'precipitation' but US forecasts more frequently specify types ('rain/snow mix').
Connotations
Identical for the main sense. The 'hasty action' sense is equally rare in both varieties.
Frequency
Slightly more frequent in US weather reporting due to detailed radar and forecast terminology.

Learning
Memory Aids
Mnemonic
Think of PRECIPICE (a steep cliff) + ACTION. Precipitation is like the sky's action of throwing water 'over the cliff' down to Earth.
Conceptual Metaphor
THE SKY IS A CONTAINER (that releases its contents); HASTE IS A FALLING OBJECT (the 'rushed action' sense).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'осадки' (only for weather/chemistry). The Russian word can colloquially mean 'sediment' or 'residue', which is 'precipitate' (noun) in English, not 'precipitation'.
- The 'hasty action' sense has no direct single-word equivalent in Russian; translate as 'поспешность', 'опрометчивость'.
Common Mistakes
- Using 'precipitation' to mean 'prediction'. (Incorrect: 'His precipitation was wrong.' Correct: 'His prediction was wrong.')
- Confusing 'precipitation' (process/noun) with 'precipitate' (verb: to cause, or noun: the solid formed).

Frequently Asked Questions
No. It is the general term for all forms of water falling from the sky, including rain, snow, sleet, and hail.
'Precipitate' is primarily a verb meaning 'to cause something to happen suddenly' or, in chemistry, 'to cause a solid to separate'. 'Precipitation' is the noun for the process or result (the weather event or the chemical solid).
No, it is quite formal and literary. In modern usage, the weather and chemistry senses are vastly more common.
In British English: pri-SIP-i-TAY-shun. In American English: pri-SIP-uh-TAY-shun. The main difference is the vowel in the third syllable.
