Etymology
the word 'spawner' is a transparent english compound built from the verb 'spawn' and the agentive suffix '-er'. the verb 'spawn' has a murky middle english origin, likely entering the language from the anglo-norman espandre, meaning "to spread out". this sense evolved logically into the biological act of fish spreading or shedding their eggs into the water. the addition of the productive old english agent suffix '-er', which itself has a deep indo-european lineage via latin and germanic, creates a noun meaning "one who spawns". thus, the term moved from a general action of spreading to a specific biological function, and finally to a label for the creature performing that function, later extended metaphorically to any source that generates new things.
Analysis
Structure: spawn (to produce eggs) + er (agent suffix)
spawn: from middle english spanen, of uncertain origin, possibly related to anglo-norman espandre or old french espandre meaning "to spread out, shed". in english, it came to specifically mean "to produce or deposit (eggs)".
er: from old english -ere, a suffix forming agent nouns (one who does or works with something), from proto-germanic -ārijaz, likely borrowed from latin -ārius.
