Etymology: "Buildup" is a deverbal noun, meaning it was formed from the phrasal verb "build up" by turning the verb into a noun. The pattern is an ordinary one in English: a verb-plus-particle phrase such as "set up," "break down," or "lock out" gives rise to a noun that names the action or its result. Here the verb "build up," meaning to construct gradually or to increase in amount, became the noun for that gradual process itself. The noun keeps the verb's sense of slow accumulation. A buildup of pressure, traffic, or troops is something that grows bit by bit until it reaches a notable size or intensity, which is exactly the meaning the word carries today. The compound form is written as one word, but the source does not record a precise date for when that spelling was adopted, so nothing more can be said about its first appearance.
