How It Works

In linguistic studies, this usage accounts for approximately 35% of all 'of' occurrences in modern English texts. The preposition creates genitive relationships without using the apostrophe-s construction.

Quantification and Measurement: 'Of' connects quantities to what they measure, appearing in phrases like 'three pounds of apples' or 'a gallon of milk.' This mathematical relationship function appears in approximately 20% of 'of' uses. The preposition creates partitive constructions that specify portions of wholes.
