Grammatical Overview
By is a highly versatile and frequent preposition and adverb in the English language, serving as a critical structural driver across multiple grammatical frames. Primarily, it establishes the agent in passive voice constructions (e.g., The book was written by Jane). It also acts as a primary marker for method or means, frequently colligating with gerunds (e.g., You can improve by practicing). Additionally, it functions as a spatial preposition indicating proximity (down by the river) and a temporal preposition setting strict deadlines (finish by Friday).
