Etymology
The verb 'prop' emerged in Middle English around the 15th century, likely derived from the Middle Dutch word 'proppe', meaning 'support' or 'vine prop'. Its ultimate origin is uncertain but is thought to be imitative or expressive in nature, perhaps related to the concept of something being thrust or stuck in place to provide support. This core idea of providing physical support expanded metaphorically to describe any person or thing that serves as a mainstay or source of assistance. The word's concise form and direct meaning have remained remarkably stable from its probable Low German roots into modern English usage.
Analysis
The word 'prop' is a simplex word of Germanic origin. It functions as a complete lexical unit.
