 INTRODUCTION
We made out this work with the purpose of knowing and identifying auxiliaries and modals
verbs, in this way we can communicate in a clearer way and we can understand when to
use them, for example Modal verbs and auxiliary verbs are verbs that help other verbs to
show meaning. Auxiliary verbs indicate information such as tense, mood, voice and other
grammatical aspects of the action. Modal verbs are a type of auxiliary verbs that indicate
the modality They express attitudes such as ability, possibility, permission, and suggestion.
In or opinion we think that t’s not possible to communicate effectively in the English
language without frequently using such modal verbs, a student that wishes to become an
effective academic should study this word type carefully, most of a proposition’s meaning is
contained within a verb and its associated nouns, verbs are one of the most important word
classes for speakers of English
 AUXILIARIES
What is the auxiliary verb
Examples
In English grammar, an auxiliary
verb is a verb that determines the "Be", "Do", and "Have"
mood, tense, voice or aspect of
another verb in a verb phrase.
Auxiliary verbs include be, do and
have along with modals such as
can, might and will and can be
contrasted with main verbs and
lexical verbs
To determine the verb tense in which an idea is
expressed. In Spanish we do this through the
conjugation of the verb; however, in English we
mainly use the auxiliaries for this purpose. I will
present some examples to make it clearer:

Did you go to Istanbul (Past tense)?

Are you going to Istanbul (Present)?
Are you going to Istanbul? (Future)
 THERE ARE THREE EXCEPTIONS TO THIS RULE:

Knowing the correct use of auxiliary verbs is

key to the use of verb tenses. Each verb tense
has an auxiliary form of the verb.

Present simple positive: She works in a bank.

Positive past simple: She bought a new television last week.
The positive imperative statements: Hurry up!
 MODALS
Modal verbs show possibility, Modal verbs are quite common in
intent, ability, or necessity. English, and you’ve probably seen
Because they’re a type of them hundreds of times without
auxiliary verb (helper verb), knowing their name. The most
they’re used together with frequently used ones are:
the main verb of the sentence Can, Could, May, Might, Should,
Would, Must, Wil, Ought to.
May I leave early today?
Could I play too?
You should try the lasagna. Exceptions:
Would you get that box off the top shelf? There are more modal verbs, although
Will you turn that music down? the ones above are the most common.
Some modal verbs are outdated and
rarely used—like shall and ought to
—while others are more colloquial—
such as got to, need to, or have to.

 SEMI-MODALS
What are Semi-Modals? We call semi-modals some verbs
that can be both modal, function as ordinary verbs, or
share some particularity with them. There are 3 semi-
modals that are characterized by :

Dare Need Ough to

DARE NEED
The verb dare is translated as dare
Need expresses need and can function in two

different ways: as a modal verb and as a

normal verb.
As a modal verb it appears most often As a modal verb, its most common use is in
in the negative form. In this case, it is the negative form, that is, needn't (need not)
followed by the infinitive without to: followed by the infinitive without to:
I daren't (dare not) do it.
Furthermore, dare can behave as a You needn't go.

such, it needs the auxiliary verb do to
form the negation and the In addition, this verb behaves as a normal
interrogative and is followed by the verb in the affirmative, negative and
infinitive with to. interrogative forms. As such, it needs the
I don’t dare to do it. auxiliary do and is followed by to
 SEMI-MODALS (EXAMPLES)
OUGH TO
We consider ought to a semi-modal verb
because it is followed by the particle to,
whereas, as a general rule, modal verbs do
not have this particle. The negation of ought to
is ought not to, or oughtn't to.

We use it to give advice or recommendations.

In this case, it is similar to should:

You ought to take care of yourself.

To speak of probabilities:

They ought to be here soon.

 MY LEARNING

Modal and semi-modal verbs are important for all those who
speak English, there are those who even have no idea what these
verbs are called, as in my case, they are extremely important
modifiers, so much so that they can modify the meaning of a
sentence so you know what they are and how to apply them is
extremely important when speaking and writing.
