Essential Spanish Grammar: Adjectives, Verbs, and Sentence Structures

Adjective Meanings and Functions

Adjectives describe the properties of beings. Some adjectives function to define relationship qualities. Adjectives do not always denote the complete and accurate signification of the noun with which they agree.

Types of Adjective Values

• Specified Value: Indicates a property that distinguishes the being or object designated by the noun.
• Explanatory Value: Describes a property of the being or object without intending to distinguish it from others.
• Ornamental Epithet: A poetic and evocative adjective used for suggestive power.

Verbal Aspect

The speaker can refer to an action observed in its beginning, development, completion, results, or reiteration. This gives rise to different aspectual meanings, involving both compound and simple forms. Simple forms are exclusively imperfective.

Verbal Mode

Verbs can be viewed in three ways:

1. Indicative: As a reality.
2. Subjunctive: As a virtuality.
3. Imperative: As an order.

Voice

Voice is expressed through syntactic procedures:

• Active Voice: The subject is the agent of the action.
• Passive Voice: The subject is not the agent of the action.

Verbal Periphrasis

A construction made up of two verb forms: an auxiliary verb and a main verb. The auxiliary verb carries the morphemes of person, number, and time, while the main verb carries the lexical meaning.

Aspectual Classes

• Developmental Periphrasis: Includes durative, finished, and reiterative actions.
• Manner Periphrasis: Expresses necessity, obligation, possibility, or probability.

Sentence Classifications

Attributive Sentences

Use verbs such as ser (to be), estar (to be), and parecer (to seem) with a mandatory attribute.

Semi-attributive Sentences

A construction halfway between attribution and predication.

Predicative Sentences

• Transitive: Require a direct object (CD) to clarify meaning.
• Intransitive: Possess meaning in themselves and do not require a direct object.

Active and Passive Constructions

• Periphrastic Passive: Uses the verb ser + participle, agreeing in number and gender with the subject.
• Reflexive Passive: Uses the pronoun se as a syntactic frame of passivity.
• Reflexive Sentences: The subject performs an action that falls on the same person or thing.
• Pronominal Intransitive Constructions: Verbs that only appear as pronominal or can be used without the unstressed pronoun.

Phrases

• Nominal Phrases: e.g., "weekend dog."
• Adjective Phrases
• Verbal Phrases
• Adverbial and Prepositional Phrases: e.g., "through."
• Conjunctive Phrases: e.g., "unless."
