This paper contributes to the growing body of literature on nouns of measurement and the multifaceted processes that they are susceptible to undergo. It spotlights the Russian prepositional phrase po mere, lit. ‘by measure’, which originally held a compositional meaning referring to size measurement but has shifted towards a relator function as a temporal preposition marking simultaneity. The paper unravels the grammaticalization mechanisms behind this development by tracing across three centuries the constructional change, the entrenchment of the new temporal function and its eventual dominance over the older uses, based on the Russian National Corpus data.

从尺寸测量到同时性：俄罗斯 po 的案例仅仅是“按测量”

本文为越来越多的关于测量名词及其容易经历的多方面过程的文献做出了贡献。它突出了俄语介词短语po mere , lit。'by measure' 最初具有组合意义，指的是尺寸测量，但已转变为作为时间介词标记同时性的关系者功能。本文根据俄罗斯国家语料库的数据，通过追溯三个世纪的结构变化、新时间功能的巩固及其对旧用途的最终主导地位，揭示了这一发展背后的语法化机制。
