• Ad positions, a class of words that consists of prepositions and post positions, are used to convey geographical or temporal links or denote different semantic responsibilities. Its complement, or occasionally object, is the noun phrase that a preposition or post position usually joins with.
• To indicate direction, time, place, location, spatial relationships, or to introduce an object, a preposition is a word or set of words used before a noun, pronoun, or noun phrase. Prepositions include phrases like "in," "at," "on," "of," and "to."

The different types of prepositions are:

• Prepositions of Place.
• Prepositions of Time.
• Prepositions of Direction.
• Prepositions of Location.
• Prepositions of Spatial Relationships.
• Prepositional Phrase.

hence I don't usually work on weekends.
