Technical
Core term in aerospace, mechanical engineering, and pyrotechnics for the component that initiates combustion.

Learning
Memory Aids
Mnemonic
Think of IGNITE + R (like 'starter'). The R at the end makes it the 'thing' or 'person' that does the igniting.
Conceptual Metaphor
INITIATION IS IGNITION; A PERSON/THING THAT STARKS A PROCESS IS A SPARK/SOURCE OF FIRE.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'поджигатель' which has a strong negative connotation of 'arsonist'. 'Igniter' is neutral/technical. For a person starting a fire criminally, 'arsonist' is correct. For a device, use 'воспламенитель' or 'запал'.
Common Mistakes
- Confusing 'igniter' (noun, thing) with 'ignite' (verb).
- Misspelling as 'ignitor' (common variant, not a mistake).
- Using figuratively where 'catalyst' or 'instigator' would be clearer.
