Definition of “For”
The preposition “for” is a word that connects nouns, pronouns, and phrases to other words in a sentence to indicate a relationship. It is a versatile preposition with multiple meanings, often indicating purpose, reason, duration, or recipient. Understanding the various contexts in which “for” is used is essential for effective communication.
Key characteristics of “for”:
- It is a preposition, meaning it typically precedes a noun or pronoun (the object of the preposition).
- It expresses a relationship between the object of the preposition and another element in the sentence.
- Its meaning varies depending on the context.
Functions of “For”
“For” performs several key functions in English grammar, making it a crucial part of sentence construction. Its primary functions include:
- Indicating Purpose: Explaining the reason or intention behind an action.
- Indicating Duration: Specifying the length of time something lasts.
- Indicating Recipient: Identifying who or what receives something.
- Indicating Reason: Providing the cause or explanation for something.
- Indicating Exchange: Showing what is given or received in return for something else.
Structural Breakdown
The basic structure involving “for” is: [Main Clause] + for + [Noun/Pronoun/Gerund Phrase]. The element following “for” is the object of the preposition. Understanding this structure helps in identifying the role “for” plays in connecting different parts of the sentence.
Consider the following example: “I bought a gift for my mother.” In this sentence:
- “I bought a gift” is the main clause.
- “for” is the preposition.
- “my mother” is the object of the preposition, indicating the recipient of the gift.
The phrase “for my mother” is a prepositional phrase, which acts as an adverbial modifier, providing additional information about the verb “bought.”
Types of “For” Usage
The preposition “for” is used in a variety of contexts. Here’s a breakdown of the different types of usage:
For Indicating Purpose
When used to indicate purpose, “for” explains the reason or intention behind an action. It often answers the question “Why?” regarding a particular activity. The structure is typically: Verb + for + Gerund (-ing form of the verb) or Noun + for + Gerund.
Example: “I use this knife for cutting vegetables.” Here, “for cutting vegetables” explains the purpose of the knife.
For Indicating Duration
In this context, “for” specifies the length of time that something lasts. It answers the question “How long?” It is commonly used with perfect tenses. The structure is usually: Verb + for + Period of Time.
Example: “I have lived in this city for five years.” Here, “for five years” indicates the duration of the speaker’s residence.
For Indicating Recipient
“For” can identify who or what receives something. It answers the question “Who is this for?” In this case, the structure is: Verb + Noun + for + Recipient.
Example: “She baked a cake for her friend.” Here, “for her friend” indicates who the cake was baked for.
For Indicating Reason or Cause
When indicating reason or cause, “for” provides an explanation for something. It is often used synonymously with “because of” or “due to.” The structure is: Adjective/Noun + for + Reason.
Example: “He was praised for his hard work.” Here, “for his hard work” explains the reason for the praise.
For Indicating Exchange or Substitution
“For” can also show what is given or received in return for something else, indicating an exchange or substitution. The structure is: Verb + for + Exchanged Item.
Example: “I traded my old car for a new one.” Here, “for a new one” indicates what was received in exchange.
For Indicating Direction or Destination

Usage Rules of “For”
Understanding the rules governing the use of “for” is crucial for avoiding grammatical errors. Here are some key rules to keep in mind:
- “For” must be followed by a noun, pronoun, or gerund. Incorrect: “I am here for to help.” Correct: “I am here for helping.”
- When indicating duration, “for” is used with a specific period of time. Incorrect: “I have been waiting since two hours.” Correct: “I have been waiting for two hours.”
- Avoid using “for” interchangeably with “to” when indicating purpose. While both can express purpose, “to” is often followed by the base form of a verb, while “for” is followed by a gerund. Example: “I went to the store to buy milk.” vs. “I went to the store for buying milk” (less common, but grammatically correct).
- In some cases, “for” can be omitted in informal speech or writing, especially before “because.” Example: “I can’t go, I’m busy.” (instead of “I can’t go, for I’m busy.”)

| I waited him for an hour. | I waited for him for an hour. | The preposition “for” is necessary before the pronoun “him”. |
