Grammatical Classification of Sentences and Statements

Fundamentals of Statements and Sentences in Grammar

Defining the Statement (Enunciado)

A statement is a short text set in a particular communicative context, possessing a meaningful structure. Statements include:

• Interjections: Unchanging expressions that often convey the speaker's condition (proper and improper interjections).
• Exclamatory Expressions: Marked with an exclamation point; their meaning varies depending on the context.
• Answers to questions posed earlier.
• Elliptical fragments that can easily be converted into full sentences.
• Nominal Sentences: Elliptical sentences where the missing element is the verb (e.g., sayings and headlines).
• Sentences, which, along with phrases and words, are the basic unit in grammatical analysis.

Characteristics of the Grammatical Sentence (Oración)

A sentence is a type of statement characterized by three essential facts:

1. Presence of at least one verb in a personal form.
2. Organization into two basic constituents: the subject and the predicate. The predicate is essential in all cases, while the subject allows for several possibilities:
   • Subject prepended to the explicit predicate.
   • Subject postposed to the explicit predicate.
   • Subject inserted within the explicit parts of the predicate.
   • Implicit Subject (omitted).
   • No Subject (verb used impersonally).
3. Grammatical person and number agreement between the verb and the subject in a personal form.

Sentence Modality (Modality Enunciativa)

The enunciative modality refers to the insertion of the sentence into the context of real communication and the attitude of the speaker towards what is said and how the receiver processes the message. Modality is influenced by:

• Intonation: Represented by punctuation in written language.
• Verbal Mode: Expressing different facts, hypothetical situations, and orders.
• Order of appearance of certain words or terms (word order).

Classification of Sentences

Sentence Types Based on Modality

Sentences are classified according to their enunciative mode:

Declarative Sentences

These sentences state a fact. They use descending intonation, and the verbal mode is typically indicative.

• Affirmative: Yes, they just left the train.
• Negative: I have not seen them leaving the train.

Interrogative Sentences

These sentences pose a question. They use rising intonation and the appropriate verbal mode.

• Total or Partial
• Direct or Indirect
• Rhetorical
• Confirmatory

Imperative Sentences

These sentences convey a command or prohibition. They use a sudden downward intonation, similar to or more emphatic than declarative sentences. The verbal mode is imperative in the affirmative and subjunctive in the negative. An exhortative sentence raises an invitation.

Exclamatory Sentences

These sentences express emotion or mood. They use emphatic intonation, changes in the melodic curve, and are often introduced by an exclamatory word. The verbal mode is usually indicative.

Optative Sentences

These sentences express a wish, often utilizing the subjunctive mood.

Sentence Types Based on Verb Characteristics

• Predicative Sentences: Contain an explicit predicate that expresses the action carried out by the subject.
• Attributive Sentences: Contain a copulative verb or quasi-copulative verb.
• Impersonal Sentences: Often describe atmospheric phenomena or use verbs impersonally.
• Inaccusative Sentences: Characterized by a predicate followed by a postposed subject, where the subject exhibits features more characteristic of a complement.
