C1Formal / Technical
Definition
Meaning
The temperature at which a material will spontaneously ignite and sustain combustion.
Figuratively, the critical moment or condition where a significant event or reaction becomes inevitable.
Linguistics
Semantic Notes
Primarily a technical term in chemistry, physics, and engineering. Its figurative use is a clear conceptual metaphor based on the physical process.

Usage
Context Usage
Business
Rarely used, except possibly in high-risk industry reports or metaphorical descriptions of market crises.
Academic
Common in chemistry, physics, and engineering papers and textbooks.
Everyday
Very rare. Might appear in news reports about fires or figurative descriptions of social unrest.
Technical
The primary context. Precisely defined in safety data sheets, combustion studies, and material science.
Examples
By Part of Speech
verb
British English
- The mixture failed to ignite-point under those conditions.
American English
- The mixture failed to ignition-point under those conditions.
Examples
By CEFR Level
- The paper will not burn because it is below its ignition point.
- Safety protocols require storing the chemical well below its established ignition point.

Learning
Memory Aids
Mnemonic
Think of a car's 'ignition' (where you start the engine) combined with the 'point' of no return. It's the exact *point* where something *ignites*.
Conceptual Metaphor
SOCIAL/EMOTIONAL SITUATION IS A COMBUSTIBLE MATERIAL (e.g., 'The protest reached its ignition point after the arrest.')

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating word-for-word as "точка зажигания" in figurative contexts, where "переломный момент" or "критическая точка" is more natural.
- Do not confuse with "температура вспышки" (flash point), which is a related but distinct technical term.
Common Mistakes
- Using 'ignition point' interchangeably with 'boiling point' in metaphors.
- Incorrect preposition: 'at the ignition point' (correct) vs. 'on the ignition point' (incorrect).

Frequently Asked Questions
No, they are related but distinct. The flash point is the temperature at which a material gives off enough vapour to ignite briefly when exposed to a flame. The ignition point (or autoignition temperature) is higher—it's the temperature at which the material will ignite spontaneously without an external flame.
No, 'ignition point' is exclusively a noun phrase. The related verb is simply 'ignite'.
It is not extremely common but is readily understood, especially in analytical writing about conflicts, crises, or social movements. It carries a dramatic connotation of sudden, irreversible change.
The ignition point is a defined material property typically found in technical data sheets (TDS), material safety data sheets (MSDS/SDS), or engineering reference handbooks. It is determined through controlled laboratory testing.
