The document discusses the differences between modal verbs such as should, must, have to. It explains that should and must are true modal verbs that do not require auxiliaries, while have to is a semi-modal verb that behaves like a regular verb. It provides examples of how each is used and notes specific rules for their formation, negation, and combinations with other verbs.

Modal verbs are a category of auxiliary verbs in English grammar that play a unique and crucial role in expressing attitudes, degrees of necessity, possibility, ability, permission, and more. They work alongside main verbs to modify or enhance the meaning of a sentence, providing nuanced shades of meaning and indicating the speaker's viewpoint. Here's a description to help you understand modal verbs:
1. Expressing Modality:
Modal verbs are used to convey the speaker's attitude, opinion, or the way an action is seen from their perspective. They add layers of meaning to sentences by indicating how certain, likely, necessary, or possible an action is. Modality can be divided into several categories:
2. Possibility and Probability:
Modal verbs such as "can," "could," "may," "might," and "shall" are used to express degrees of possibility and probability.
Example: She may join us for dinner.
3. Necessity and Obligation:
Modal verbs like "must," "have to," and "should" are employed to denote necessity, obligation, or strong recommendation.
Example: Students must complete their assignments.
4. Ability and Permission:
Modal verbs such as "can" and "could" indicate someone's ability to perform an action, while "may" and "might" can express permission or give someone the right to do something.
Example (Ability): He can speak multiple languages.
Example (Permission): You may use my laptop.
5. Requests and Offers:
Modal verbs like "will" and "would" are used to make requests or offers, indicating willingness or the speaker's intention.
Example (Request): Would you please pass me the salt?
Example (Offer): I will help you with your project.
6. Deduction and Inference:
Modal verbs like "must" and "might" are used to express deductions or inferences based on available evidence.
Example: He's wearing a raincoat, so it must be raining.
7. Politeness and Formality:
Modal verbs can contribute to the tone of a sentence, making it more polite or formal.
Example: Could you kindly provide me with some information?
Modal verbs are distinct from main verbs in that they lack certain tenses and forms. They are always followed by the base form of the main verb and do not add "-s" in the third person singular. Understanding modal verbs allows you to convey a wide range of meanings, attitudes, and intentions in your communication, making your language more expressive and effective.

LIN020L007A Syntax and Morphology
Tahmina Haque Modal VerbsA modal verb, also known as a modal auxiliary, is a type of auxiliary verb that is used to indicate modality. In 'Understanding English Grammar' Payne defines modality as a complex conceptual domain. Many researchers have written on defining auxiliarihood and modaity ( Palmer 1986; Nagle 1989; Heine 1993). There is no correct way to define modality because of its highly distinctive and variable feature. Palmer (1986: 4) tries to explain the reason:'The real problem with modality is just not that there is great variation in meaning across languages but that there is no clear basic feature.' Modality is not only marked by modal verbs, it is also marked by mood and by particle and clitics. All these together make the syntax and semantics of modality one of the biggest problem for grammatical analysis.In this essay English modal verbs and their general characteristics are brought together followed by their complex effect in the language in terms of meanings and their general use in communication. Modal verbs are members of a large set of auxiliary verbs which have some common characteristics. Below is a table listing the modal verbs and their classification ( Quirk et al. 1985: 137):Class of verbsExamples CENTRAL MODALSMARGINAL MODALSMODAL IDIOMSSEMI-AUXILIARIES can, could, may, might, must, shall, should, will, woulddare, need, ought to, used tohad better, would rather/ sooner, BE to, HAVE got to, etc

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Should and Must are real modal verbs, and therefore,
like all modal verbs:
They are always followed by the “Infinitive without to”.
Should do, Must do
They are the same for all the pronouns:
I should, he should, it should etc.
3. Should and Must are real modal verbs, and therefore, like all modal verbs:
Do not need auxiliaries. They take direct negative and
question forms
I Should not (Shouldn´t). We must not (mustn´t)
Should I? Must we?
Never combine with another modal verb:
You should can You should be able to…
He will must He will have to…
4. “Have to” is a semi-modal verb. It is like a modal verb because it
fulfils specific function, but it behaves like an ordinary verb in its
formulation:
It is followed by the infinitive “Without to”:
Have to do
It is conjugated according to pronouns:
I have to, he has to, etc.
5. “Have to” is a semi-modal verb. It is like a modal verb because it fulfils
specific function, but it behaves like an ordinary verb in its formulation:
It needs auxiliaries. It doesn´t take direct negative and question
forms
I don´t have to . She doesn´t have to
Do I have to? Does she have to?
It can combine whit modal verbs:
You will have to, he might have to.
6. I believe teachers should have higher salaries.
You look Tired. I think you should have some rest.
He shouldn´t make a rushed decision.
Do you think we should phone her?
What should I say when I speak to him?
7. He should arrive any minute.
He should be long now.
He shouldn´t have arrived by now.
8. You should have been more careful.
I shouldn´t have said that.
9. Note 1:
“Ought to” is a synonym for “should”.
It generally sounds more formal than
“should”, and is less commonly used
particularly in the question form:
10. Note 2:
Should (but not Ought to ) is also express a small
possibility.
- If I should ever go back there, I will not make the
same mistake again.
- Should you need any further assistance, do not
hesitate to contact me. (Formal writing)
11. He is very ill. You must call a doctor now.
We must not (mustn´t) lose the match tomorrow, or
we will be out of the tournament.

too.
You mustn´t hesitate to call me if you need help.
12. You must not (mustn´t) use your mobile devices
during take off.
You must not be late for your interview tomorrow.
13. You must be tired after your very long day.

a doctor.

him.

retake it.
17. Note 1:
As you can see, the main difference between “must”
And “Have to” is that “must” is a necessity felt by the
speaker, whereas “have to” is an external obligation or
rule. If this difference is not relevant, you can use
“must” and “have to”, Interchangeably in positive
sentences.
18. Note 1:
However, be careful that in the negative “must not”
Is still a necessity or an obligation “NOT TO” do
something (a prohibition), whereas “don´t have to”,
removes the necessity or obligation.
19. Note 2:
As “must” has no past tense, both obligation and
necessity are expressed whit “had to” in the past.
20. Note 3:
“Need to” is a softer alternative to both, “must” and
“have to”:
- I must/need to finish this tonight, because I want to
take tomorrow off.
- I have to/need to finish this tonight. My deadline is
tomorrow.
- Do I need to finish this tonight? I don´t need to
finish this tonight.
21. Note 3:
You may also come across the modal verb “Need ”. It
is a very common modal verb, and can only be used in
negative sentences and questions:
- Do I need to finish this? = need I finish this?
- I don´t need to finish this = I needn´t to finish
this.
