Prepositions of time are used to show when something happened. As we saw in the previous lesson, the three most common prepositions (“in”, “at”,“on”) can be used both as prepositions of place or time. Below are several other common prepositions of time.
Meaning: preceding, earlier than
Meaning: subsequent to in time
Meaning: throughout the duration of or at a point in the course of
Meaning: a function word used to indicate duration of time, how long something has happened
Use: Although the meaning of “for” is similar to “during”, in the sense of indicating a duration of time, “for” is used to express a period of time (hours, days, months, years, etc.) while “during” is used to express when something happened (within a period of time).
Note: We will learn more about prepositions of time in later lessons on the various verb tenses.
