Etymology
The word "flashbulb" is a transparent Modern English compound, seamlessly combining two existing nouns to name a new technological object. The first element, "flash," evokes the brief, intense burst of light characteristic of early photography. The second element, "bulb," draws from its botanical and later electrical sense of a rounded glass vessel, describing the physical shape of the light source. This logical construction perfectly captures the device's primary function: a bulb designed to produce a flash. The term's later psychological meaning, "flashbulb memory," is a metaphorical extension, comparing the startling clarity and permanence of such a memory to the sudden, illuminating effect of the photographic flash.
Analysis

- bulb: From Latin bulbus, meaning "bulb, onion," via Greek bolbos. In this compound, it functions as the head noun, denoting the physical object, a rounded glass enclosure.
