Ever wondered about the hidden helpers of language that aren't quite modal verbs?
Understanding Quasi-Modals
Quasi-modals are a group of verbs or phrases that function similarly to modal verbs but are not considered true modals. Instead, they share some characteristics with modal verbs while exhibiting distinct syntactic behaviors or having a more limited range of usage.
Common Examples of Quasi-Modals
Have to: Expresses obligation or necessity.
Need to: Indicates necessity or requirement.
Ought to: Suggests obligation or advisability.
Used to: Refers to past habits or states.
Dare: Conveys challenge or permission.
Be able to: Indicates capability or possibility.
Less Common Quasi-Modals
Have got to: Similar to "have to," commonly used in British English.
"I've got to finish this report by tomorrow."
Be supposed to: Indicates obligation or expectation.
"You're supposed to arrive early for the meeting."
Be likely to: While not always considered a true quasi-modal, "be likely to" can express possibility or probability.
"It's likely to rain tomorrow."
These quasi-modals may vary in usage and prevalence depending on regional dialects and contexts. While the list provided includes the most recognized quasi-modal verbs and phrases, there may be other expressions that could be considered quasi-modals depending on interpretation. However, the ones listed are the most widely acknowledged and studied in linguistic literature.

Similarities to modals
Like modal verbs (can, must, will, etc.), quasi-modals express things like necessity, obligation, possibility, or advice.
Differences from modals
Conjugation Quasi-modals can be conjugated for tense (past, present, future) and person (I, you, he/she/it, etc.) unlike modals.
Negatives and questions They can use helping verbs like "do" to form negatives and questions, which modals typically don't.
Example
The key difference between the quasi-modal "will have to" and the modal verb "must" in the example sentence "She will have to wait in line for a while, as the store is very busy today." lies in the specificity of obligation and the time frame.
"Will have to" (quasi-modal)
Expresses a future obligation based on the circumstances. It implies a strong likelihood that waiting is unavoidable due to the store being busy.
Can be conjugated for tense (will have to in this case) and person (she in this case).
"Must" (modal verb)
Expresses a more general obligation or necessity. It doesn't necessarily specify the time frame and simply conveys that waiting is required.
Does not conjugate for tense or person. It remains "must" regardless of the subject or time frame.
Breakdown of how the meaning changes
"She will have to wait..." - This sentence implies the busyness of the store creates a situation where waiting is highly likely and almost unavoidable.
"She must wait..." - This sentence simply states that waiting is a requirement, but it doesn't give any reason or specify the time frame. It could be a general rule or a one-time situation.
In conclusion, "will have to" (quasi-modal) provides a more nuanced future obligation based on the context, while "must" (modal) expresses a more general and timeless necessity.
How quasi-modals can be conjugated present past and future?
A general overview of how some common quasi-modals can be conjugated across different tenses
Quasi-modals can be conjugated similarly to regular verbs in terms of tense (present, past, future) and person (first person, second person, third person). However, the conjugation may vary slightly depending on the quasi-modal in question.
1. Present Tense
- Have to: I have to, you have to, he/she/it has to, we have to, you have to, they have to.
- Need to: I need to, you need to, he/she/it needs to, we need to, you need to, they need to.
- Ought to: I ought to, you ought to, he/she/it ought to, we ought to, you ought to, they ought to.
- Be able to: I am able to, you are able to, he/she/it is able to, we are able to, you are able to, they are able to.
2. Past Tense
- Have to: I had to, you had to, he/she/it had to, we had to, you had to, they had to.
- Need to: I needed to, you needed to, he/she/it needed to, we needed to, you needed to, they needed to.
- Ought to: I ought to (no change in form for past tense).
- Be able to: I was able to, you were able to, he/she/it was able to, we were able to, you were able to, they were able to.
3. Future Tense
- Have to: I will have to, you will have to, he/she/it will have to, we will have to, you will have to, they will have to.
- Need to: I will need to, you will need to, he/she/it will need to, we will need to, you will need to, they will need to.
- Ought to: I will ought to (less common; "ought to" typically remains the same in future tense).
- Be able to: I will be able to, you will be able to, he/she/it will be able to, we will be able to, you will be able to, they will be able to.
It's important to note that while some quasi-modals, like "ought to," don't change form for past tense, others, like "have to" and "need to," do change form. Additionally, some quasi-modals, like "be able to," use forms of the verb "to be" for conjugation. These conjugation patterns should be applied according to standard English grammar rules.
Quasi-modals can be conjugated for present, past, and future in a few different ways.
Using helping verbs
Many quasi-modals combine with helping verbs like "will," "have," or "did" to indicate tense.
Present
I need to finish this report by tomorrow. ("need to" expresses present obligation)
You don't have to come if you're not feeling well. ("have to" changes to negative with "do")
Past
We should have left earlier to avoid traffic. ("should" changes to "should have" for past obligation)
She used to be able to play the piano beautifully. ("used to" indicates a past habit)
Future
They will have to find another solution soon. ("have to" combines with "will" for future obligation)
He might be able to help you with that. ("be able to" expresses future possibility)
Internal changes
Some quasi-modals change their internal form to indicate tense.
Present and Future
I ought to call my mom. (present obligation) / She ought to know better. (future implication)
Past
It ought to have rained yesterday according to the forecast. ("ought" changes to "ought to have" for past)
Note
Not all quasi-modals exhibit both methods of conjugation. Some, like "ought to," only change internally, while others, like "need to," rely solely on helping verbs.
