“Should of” vs. “Should Have”: Which One Correct

English grammar often throws us curveballs, especially when it comes to common phrases and contractions. One such area of confusion involves the difference between “should of” and “should have.”

Many people use “should of” in writing and speech, but this usage is incorrect. Understanding the right phrase is crucial for clear and precise communication. Let’s dive deep into this grammatical issue, unraveling why “should of” is wrong and how to use “should have” correctly.

The Contraction Confusion: Understanding “Should’ve”

The contraction “should’ve” is a shortened form of “should have.” It’s commonly used in informal speech and writing. To understand “should’ve” better, let’s break it down:

• Definition: “Should’ve” is a combination of “should” and the contracted form of “have.”
• Usage: It’s used to express a past obligation or expectation that was not met.
• Examples:
  • “I should’ve studied harder for the exam.” (Meaning: I did not study as hard as I should have.)
  • “She should’ve called you by now.” (Meaning: She has not called you as expected.)

In both examples, “should’ve” indicates something that was expected or necessary but didn’t happen.

Historical Context of “Should Have” in the English Language

Understanding the historical evolution of “should have” helps clarify why “should of” is incorrect. Here’s a brief look into its history:

• Origins: The phrase “should have” originates from Old English. It combines “should” (a past tense of “shall”) with “have,” reflecting a past obligation or expectation.
• Development: Over time, contractions like “should’ve” became common in spoken English. While “should’ve” is acceptable in informal contexts, “should have” remains the standard in formal writing.
• Evolution: The use of contractions reflects the evolving nature of English. Contractions make speech quicker and more fluid but must be used correctly to maintain clarity in writing.

Misguided Usage: Why “Should Of” Is Always Incorrect

The phrase “should of” is a frequent grammatical mistake. Here’s why it’s incorrect:

• Grammatical Structure: “Of” is a preposition, not a verb. In the phrase “should of,” it incorrectly replaces “have,” disrupting the grammatical structure.
• Auxiliary Verbs: In English, auxiliary verbs (like “have”) are essential for forming perfect tenses and modals. “Should of” fails to serve this grammatical function.
• Misconception: The mistake often arises from mishearing “should’ve” in spoken English, where “should’ve” sounds like “should of.”

How “Should Of” Fails in English Grammar

To understand why “should of” is wrong, let’s dissect its failure in English grammar:

• Auxiliary Function: In English grammar, “should” requires the auxiliary verb “have” to form the past perfect structure. “Of” does not fulfill this role.
• Examples of Incorrect Usage:
  • Incorrect: “You should of known better.”
  • Correct: “You should have known better.”
• Grammar Rules: According to English grammar rules, auxiliary verbs are essential for creating perfect tenses. “Of” cannot replace “have” in these structures.

Examples That Illuminate the Correct Use of “Should Have”

Here are examples demonstrating correct usage of “should have” and how it contrasts with the incorrect “should of”:

• Correct Usage:
  • “They should have arrived by now.” (Expectation based on time.)
  • “I should have finished the project earlier.” (Reflecting a missed obligation.)
• Incorrect Usage:
  • “They should of arrived by now.”
  • “I should of finished the project earlier.”
• Contextual Explanations: The phrase “should have” is used to discuss missed obligations or expectations. It accurately reflects what was necessary or expected.

Dissecting the Error: “Should Of” in the Wild

Let’s explore real-life examples where “should of” appears and analyze the errors:

• In Informal Writing:
  • Example: “I should of gone to the meeting.”
  • Analysis: This example shows how “should of” is often used in casual writing. The correct form is “should have.”
• In Social Media and Blogs:
  • Example: “You should of seen the movie by now.”
  • Analysis: Such errors are common in informal digital communication. The accurate phrase should be “should have.”

Common Mistakes and How to Spot Them

Here’s a list of common mistakes involving “should of” and tips to spot them:

• Typical Mistakes:
  • “He should of told the truth.”
  • “They should of left earlier.”

  • Listen for the Contraction: If “should’ve” sounds like “should of,” double-check the context.
  • Grammar Checks: Use grammar-checking tools to catch mistakes.
  • Rewriting: Read your sentences out loud to ensure they sound correct.

The Influence of Spoken English on Writing Blunders

Spoken English heavily influences writing, often leading to grammatical errors:

• Speech Patterns: Spoken English is less formal and includes contractions and colloquial phrases that can bleed into writing.
• Regional Accents: Different accents and pronunciations can affect how phrases are heard and subsequently written.
• Bridging the Gap: Being aware of the differences between spoken and written English helps in avoiding these common blunders.

The Role of Contractions in Modern English Usage

Contractions like “should’ve” play a significant role in modern English:

• Function: Contractions make speech and informal writing more fluid and natural.
• Context: Use contractions in casual settings but prefer the full form “should have” in formal writing.
• Examples:
  • “I should’ve called you yesterday.”
  • “You should have completed the assignment on time.”
