igniter

the word 'igniter' is built upon the latin root 'ignis', meaning fire, which can be traced back to the proto-indo-european root egni-, also signifying fire. the latin verb 'ignire' (to set on fire) was formed from this root, and its frequentative form 'ignitare' (to kindle) provided the basis for the english verb 'ignite'. by adding the agent suffix '-er' to 'ignite', english creates a noun that logically denotes a device or person responsible for initiating combustion. thus, the term's evolution from a concrete concept of fire to an abstract agent of ignition is clearly mapped through its constituent parts.

Structure: ign (fire) + ite (verb suffix) + er (agent suffix) ign (from latin 'ignis', meaning 'fire'), ite (a verb-forming suffix from latin '-itare'), er (an english agent noun suffix indicating a person or thing that performs an action).
