Verb: Nominal Forms and Mood Inflections | Traditional Summary
Contextualization
Verbs are fundamental words in the construction of sentences, as they indicate actions, states, or phenomena of nature. They play a crucial role in structuring sentences, allowing expressions of time, mood, and voice to be clearly communicated. Without verbs, it would be extremely difficult to describe events, give commands, or express desires and possibilities, making written and oral communication very limited.
In addition to their basic forms, verbs have inflections that indicate different moods, such as indicative, subjunctive, and imperative, each with its own functions and uses. The indicative mood is used to express real and concrete actions, the subjunctive for hypothetical or desired actions, and the imperative for commands and requests. It is also important to understand the nominal forms of verbs, which include the infinitive, gerund, and participle, as they are essential for forming verbal phrases and for varying time and aspect in sentences.
Verb Mood Inflections
The verb mood inflections are fundamental for communication, as they indicate how the action of the verb relates to reality. There are three main verbal moods: the indicative, subjunctive, and imperative. Each of these moods has distinct characteristics and is used in specific contexts to express different nuances of meaning.
The indicative mood is used to express real actions, concrete facts, and certainties. It is composed of verb tenses that indicate when the action occurs, such as present, past (preterite), and future. Examples include 'He studies every day' (present), 'He studied yesterday' (preterite), and 'He will study tomorrow' (future).
The subjunctive mood, on the other hand, is used to express hypothetical actions, wishes, uncertainties, or situations that depend on another condition to happen. Its verb tenses include present, imperfect preterite, and future. Examples are 'I hope he studies' (present), 'If he studied, he would pass' (imperfect preterite), and 'When he studies, he will pass' (future).
The imperative mood is used to give orders, make requests, or give advice. It does not have the same variety of verb tenses as the other moods, being generally used in the present. Examples include 'Study now!' and 'Don't study too much!'
-
Indicative mood: expresses real and concrete actions.
-
Subjunctive mood: expresses hypothetical actions, wishes, and uncertainties.
-
Imperative mood: used for orders, requests, and advice.
Nominal Forms of the Verb
The nominal forms of the verb are those that are not conjugated according to person, number, or tense, as occurs in finite forms. They include the infinitive, gerund, and participle. Each of these forms has specific functions in sentence construction and in forming verbal phrases.
The infinitive is the basic form of the verb that is not conjugated. It can be used impersonally, without indicating a subject, as in 'It is important to study', or personally, indicating the subject, as in 'For me to study, I need silence'. The infinitive can be simple or inflected, depending on the context.
The gerund indicates a continuous or ongoing action. It is formed by the ending '-ando' for verbs in the first conjugation, '-endo' for verbs in the second conjugation, and '-indo' for verbs in the third conjugation. Examples include 'She is studying' and 'They were running'. The gerund is frequently used in verbal phrases to indicate continuous actions over time.
The participle is used to indicate a completed action or a state resulting from an action. It is formed by the ending '-ado' for verbs in the first conjugation and '-ido' for verbs in the second and third conjugations. Examples include 'He has already studied' and 'The books have been read'. The participle is essential in forming compound tenses, such as the perfect preterite and the future perfect.
-
Infinitive: basic and non-conjugated form of the verb.
-
Gerund: indicates continuous or ongoing action.
-
Participle: indicates completed action or resulting state.
Verbal Agreement
Verbal agreement is the relationship of harmony between the verb and the subject of the sentence, so that the verb must agree in number (singular or plural) and person (first, second, or third) with the subject. This rule is fundamental for constructing grammatically correct and clear sentences.
In the case of a simple subject, the agreement is direct: 'He studies every day' (subject in singular, verb in singular) and 'They study every day' (subject in plural, verb in plural). When the subject is compound, the general rule is that the verb must be in the plural: 'Maria and João study together'.
However, there are special cases of verbal agreement, such as when the subject is collective or distant from the verb. For example, 'The majority of students studies' (collective in singular, verb in singular) and 'The students who arrived late did not study' (subject preceded by a relative clause, verb agreeing with the subject).
Verbal agreement can also vary in constructions involving treatment pronouns, where the verb agrees with the third person: 'Your Excellency is summoned'. In expressions like 'more than one', the verb may remain in the singular: 'More than one student was absent'.

Direct agreement between simple subject and verb.

Agreement in plural with compound subject.

Special cases of agreement with collective or distant subjects.
Uses and Functions of Verbs
Verbs play a central role in the structure of sentences, serving to express actions, states, or phenomena of nature. In addition, verbs can perform different syntactic functions, such as predicate, verbal phrase, and linking verb, each contributing to the clarity and precision of communication.
As the core of the predicate, the verb is the essential element that indicates what is being said about the subject. In 'She ran', the verb 'ran' is the core of the predicate, indicating the action performed by the subject. Linking verbs, such as 'to be', 'to stay', and 'to become', connect the subject to a complement that characterizes or identifies the subject: 'She is happy'.
Verbal phrases are combinations of two or more verbs that function as a single verb. They are usually formed by an auxiliary verb and a main verb in the infinitive, gerund, or participle: 'She is going to study' (infinitive), 'She is studying' (gerund), and 'She had studied' (participle). These combinations allow for expressing nuances of time, mood, and aspect.
Verbs are also fundamental in forming compound sentences, where they can act as main or auxiliary verbs in different types of subordination and coordination. For example, in 'She said she would come', the verb 'said' is the main one in the main clause, while 'would come' is the main one in the subordinate clause.

Conclusion
In this lesson, we discussed the inflections of verb moods, understanding their different forms according to the indicative, subjunctive, and imperative. The indicative mood expresses real and concrete actions, while the subjunctive is used for hypothetical actions and wishes, and the imperative for commands and requests. This distinction is crucial for clear and precise communication.
We also explored the nominal forms of the verb, which include the infinitive, gerund, and participle. The infinitive is the basic non-conjugated form, the gerund indicates continuous actions, and the participle represents completed actions. Understanding these forms is essential for constructing verbal phrases and for varying time and aspect in sentences.
Finally, we discussed the importance of verbal agreement, which ensures harmony between the verb and subject in number and person. This rule is fundamental for constructing grammatically correct and clear sentences, allowing for effective and precise communication. The knowledge gained about verbs and their inflections is essential for writing and reading texts, as well as being applicable in various everyday situations.
