Definition of ‘As If’ and ‘As Though’
‘As if’ and ‘as though’ are conjunctions used to introduce a subordinate clause that expresses a hypothetical or unreal condition. They indicate that something is being compared to something else, often implying that the comparison is not entirely true or accurate.
They function similarly and are often interchangeable, though subtle differences in usage may exist depending on context and regional preference.
In essence, ‘as if’ and ‘as though’ create a sense of pretense, supposition, or imagination. They allow us to describe situations or behaviors that are not factual but are presented as if they were.
This makes them powerful tools for adding depth and expressiveness to our communication.
They are classified as subordinating conjunctions, meaning they connect a subordinate (dependent) clause to a main (independent) clause. The subordinate clause introduced by ‘as if’ or ‘as though’ provides additional information or modifies the main clause.
Structural Breakdown
The basic structure involving ‘as if’ and ‘as though’ is as follows:
Main Clause + ‘as if’ / ‘as though’ + Subordinate Clause
The subordinate clause typically contains a verb in the past subjunctive form, especially when expressing something contrary to fact or highly improbable. However, the tense used in the subordinate clause can vary depending on the intended meaning and the relationship to the main clause.
Here’s a breakdown of the key elements:
- Main Clause: This part of the sentence can stand alone and expresses the primary idea.
- ‘as if’ / ‘as though’: These conjunctions introduce the hypothetical or comparative element.
- Subordinate Clause: This clause provides the hypothetical situation or comparison. The verb tense in this clause is crucial for conveying the intended meaning.
The verb in the subordinate clause often takes the past subjunctive form, which is identical to the simple past form except for the verb “to be,” where “were” is used for all persons (e.g., I were, he/she/it were, we were, you were, they were). This is particularly common when expressing something that is contrary to fact.
For example:
He acts as if he were the boss. (He is not the boss, but he acts like he is.)
However, if the situation is possible or likely, the verb in the subordinate clause may be in the same tense as the main clause, or in a tense that logically follows from it.
For example:
It looks as if it will rain soon. (It is likely to rain soon.)
3. Types and Categories
The use of ‘as if’ and ‘as though’ can be categorized based on the degree of unreality or hypotheticality they express. Here are the main categories:
3.1. Contrary-to-Fact Situations
This is the most common usage, where the subordinate clause describes a situation that is known to be untrue. In these cases, the past subjunctive is typically used.
Example: She talks as if she knew everything. (She doesn’t know everything.)
3.2. Possible or Likely Situations
When the subordinate clause describes a situation that is possible or likely, the verb tense often matches the tense in the main clause, or uses a future tense form.
Example: It seems as though it is going to be a long day. (It is likely to be a long day.)
3.3. Comparisons of Manner or Appearance
‘As if’ and ‘as though’ can also be used to simply compare the manner in which someone does something or the way something appears.
Example: He ran as if his life depended on it. (He ran very fast.)
3.4. Expressing Doubt or Uncertainty
These phrases can introduce a sense of doubt or uncertainty about a situation.
Example: He looked as though he hadn’t slept in days. (It was not certain if he had slept.)

5. Usage Rules
The correct usage of ‘as if’ and ‘as though’ involves several key rules:
5.1. Subjunctive Mood
When expressing something contrary to fact or highly improbable, use the past subjunctive in the subordinate clause. This is most noticeable with the verb “to be,” where “were” is used for all persons.
Example: If I were you, I would apologize. (I am not you.)
In ‘as if’ and ‘as though’ clauses:
He acts as if he were rich. (He is not rich.)
5.2. Tense Consistency
Ensure that the tense in the subordinate clause logically relates to the tense in the main clause. If the action in the subordinate clause happened before the action in the main clause, use the past perfect.
Example: He spoke as though he had known her for years. (He knew her before he spoke.)
5.3. Real vs. Unreal Conditions
If the situation is possible or likely, the subjunctive mood is not necessary. Use the appropriate indicative tense.
Example: It looks as if it will rain later. (It is likely to rain.)
5.4. Interchangeability
In most cases, ‘as if’ and ‘as though’ are interchangeable. However, ‘as though’ is sometimes considered more formal.
Example: He looked as if/as though he was tired.
When choosing between these phrases, it can be helpful to think of them in pairs: *as if as though*, *as though vs as if*, and *as if vs as though*. While they are often interchangeable, subtle differences can appear depending on formality, tone, or regional usage. For instance, in formal writing, ‘as though’ may be preferred, whereas casual speech often favors ‘as if.’
5.5. Avoiding Double Subjunctives
Do not use a subjunctive form in the main clause when ‘as if’ or ‘as though’ introduces the subordinate clause. The subjunctive mood is only required in the subordinate clause when expressing something contrary to fact.
Incorrect: I wish he were as if he were rich.
Correct: I wish he were rich. or He acts as if he were rich.
6. Common Mistakes
Several common mistakes can occur when using ‘as if’ and ‘as though.’ Understanding these errors can help you avoid them.
6.1. Incorrect Tense Usage
Using the wrong tense in the subordinate clause is a frequent error. For example, using the present tense when the past subjunctive is required.
Incorrect: He acts as if he is the boss. (when he is not the boss)
Correct: He acts as if he were the boss.
6.2. Omitting the Subjunctive
Failing to use the past subjunctive when expressing something contrary to fact is another common mistake.
Incorrect: She talks as if she was there. (when she wasn’t there)
Correct: She talks as if she had been there.
6.3. Using ‘Like’ Instead of ‘As If’ or ‘As Though’
Using ‘like’ instead of ‘as if’ or ‘as though’ to introduce a clause is grammatically incorrect in formal writing.
Incorrect: He acted like he was the boss.
Correct: He acted as if he were the boss. or He acted as though he were the boss.
6.4. Double Subjunctives
Using a subjunctive in both the main and subordinate clauses is incorrect.
Incorrect: I wish he were as if he were rich.
Correct: I wish he were rich. or He acts as if he were rich.
6.5. Confusing with ‘If’ Clauses
While both ‘as if/as though’ and ‘if’ clauses can express hypothetical situations, ‘as if/as though’ implies a stronger sense of unreality or pretense. Be mindful of the nuance you want to convey.
Example with ‘if’: If I were rich, I would travel the world. (Hypothetical, but potentially possible)
Example with ‘as if’: He acts as if he were rich. (Implies he is definitely not rich)

8. Advanced Topics
For advanced learners, here are some more complex aspects of ‘as if’ and ‘as though’:
8.1. Inversion with ‘As If’ and ‘As Though’
In formal or literary contexts, inversion can be used with ‘as if’ and ‘as though’ for emphasis. This involves placing the auxiliary verb before the subject.
Example: He spoke as though were he a seasoned diplomat. (More formal than: He spoke as though he were a seasoned diplomat.)
8.2. Ellipsis in ‘As If’ and ‘As Though’ Clauses
Ellipsis, the omission of words that are understood from the context, is common in ‘as if’ and ‘as though’ clauses, especially when the subject and auxiliary verb are repeated from the main clause.
Example: He looked as though he might faint, and so he did. (Ellipsis: *as though he might faint*)
8.3. ‘As If’ and ‘As Though’ with Modal Verbs
‘As if’ and ‘as though’ can be used with modal verbs (e.g., could, would, should, might) to express varying degrees of possibility, ability, or obligation in the hypothetical situation.

9. Frequently Asked Questions (FAQ)
Here are some common questions about ‘as if’ and ‘as though’:
Is there a difference between ‘as if’ and ‘as though’?
In most cases, ‘as if’ and ‘as though’ are interchangeable and have the same meaning. However, some people consider ‘as though’ to be slightly more formal than ‘as if.’ The choice between them often comes down to personal preference or stylistic considerations. In general, both are widely accepted and understood.
When should I use the subjunctive mood with ‘as if’ or ‘as though’?
Use the subjunctive mood when the subordinate clause expresses a situation that is contrary to fact or highly improbable. This is particularly important with the verb “to be,” where “were” is used for all persons (e.g., I were, he/she/it were, we were, you were, they were). This indicates that the situation is not true or is very unlikely to be true.
Can I use ‘like’ instead of ‘as if’ or ‘as though’?
In informal speech, ‘like’ is often used instead of ‘as if’ or ‘as though.’ However, in formal writing and more careful speech, it is generally considered grammatically incorrect to use ‘like’ to introduce a clause. Stick to ‘as if’ or ‘as though’ in these contexts to maintain accuracy and professionalism.
What tense should I use in the ‘as if’ or ‘as though’ clause?
The tense in the ‘as if’ or ‘as though’ clause depends on the relationship between the main clause and the hypothetical situation. If the situation is contrary to fact, use the past subjunctive. If the situation is possible or likely, use the appropriate indicative tense. If the action in the subordinate clause happened before the action in the main clause, use the past perfect.
How do I avoid common mistakes with ‘as if’ and ‘as though’?
To avoid common mistakes, pay close attention to tense consistency, use the subjunctive mood when necessary, and avoid using ‘like’ instead of ‘as if’ or ‘as though’ in formal contexts. Practice using these phrases in different contexts to solidify your understanding.
What are some advanced uses of ‘as if’ and ‘as though’?
Advanced uses include inversion for emphasis, ellipsis for conciseness, and using modal verbs to express varying degrees of possibility or obligation. These techniques can add nuance and sophistication to your writing and speech.
Can ‘as if’ and ‘as though’ be used in questions?
While less common, ‘as if’ and ‘as though’ can be used in questions, typically in rhetorical questions or questions expressing surprise or disbelief. For example: “Do you act as if you own the place?”
How can I improve my understanding of ‘as if’ and ‘as though’?
Practice, practice, practice! Read examples, do exercises, and try using these phrases in your own writing and speech. Pay attention to how native speakers use them and ask for feedback on your own usage. The more you practice, the more confident and accurate you will become.
