Preposition of Time

Top

A preposition of time is a preposition that permits you to discuss or converse a specific time period such as a date on the calendar, one of the days of the week, or the actual time a certain thing takes place. Prepositions of time are the same words as prepositions of place, however they are used in a different way. You can easily make a distinction of these prepositions, as they always talk over times rather than places. Prepositions of time - here's a list of the time words that need 'on', 'in', 'at' and some that don't need any preposition. Be cautious - many students of English use 'on' with months (it should be 'in'), or put a preposition before 'next' when we don't need one. Prepositions of time agree to to tell your readers when things are taking place. They are essential parts of speech to use in stories, as well as when writing simple communications, reports, stories and other items.

Mine is ON September 16. When do you eat lunch? I usually eat it AT noon. When does the school year begin in your country? In mine it begins IN July.
