The mood of a verb (sometimes called the mode of a verb) is a property that relates to how the person using the verb feels about its factuality or likelihood; the distinction is made much more often in Spanish than it is in English. The voice of a verb has more to do with the grammatical structure of the sentence in which it is used in and refers to the connection between a verb and its subject or object.
The three moods: Both English and Spanish have three verb moods:
- The indicative mood is the "normal" verb form used in everyday statements. In a sentence such as "I see the dog" (Veo el perro), the verb is in the indicative mood.
- The subjunctive mood is used in many statements that are contrary to fact, are hoped for or are in doubt. This mood is by far more common in Spanish, since it has mostly disappeared in English. An example of the subjunctive in English is the verb in the phrase "if I were rich" (si fuera rico in Spanish), which refers to a contrary-to-fact condition. The subjunctive is also used in a sentence such as "I request that my pseudonym be published" (pido que se publique mi seudónimo), which indicates a type of desire.
- The imperative mood is used to give direct commands. The short sentence "Leave!" (¡Sal tú!) is in the imperative mood.
More about the subjunctive mood: Because it is so frequently necessary in Spanish yet unfamiliar to English speakers, the subjunctive mood is an endless source of confusion for many Spanish students. Here are some lessons that will guide you through its usage:
- Introduction to the subjunctive mood: This lesson gives examples of when the subjunctive mood is used and compares them with sentences in the indicative mood.
- In the mood: A more detailed list of examples where the subjunctive mood is used.
- Tenses of the subjunctive mood: Tenses in the subjunctive mood are seldom intuitive.
- Conjugation of the subjunctive mood.
- Future subjunctive: The future subjunctive is very rare in Spanish and is archaic in most uses, but it does exist.
- Subordinate conjunctions: Verbs in dependent clauses are often in the subjunctive mood.
- Translating "might": Sentences translating the English auxiliary verb "might" often are uses a clause in the subjunctive mood.
- I don't believe ...: The negative form of the verb creer ("to believe") is typically followed by a verb in the subjunctive mood.
- Ways of making requests: The imperative and subjunctive moods aren't as distinct in Spanish as they are in English, and the subjunctive is often used to make requests.
- Sentence structure and the subjunctive: Although the subjunctive usually isn't used to refer to actual, real events, it can be when the structure of the sentence so requires.
- Statements of necessity: Verb phrases such as es necesario que ("it is necessary that") are generally followed by a verb in the subjunctive mood.
- Statements of fear: These are sometimes followed by a verb in the subjunctive mood.
- Use with opinar: Although the subjunctive mood is usually used in giving opinions, it usually isn't used with opinar.
When the passive voice is used, the subject of the sentence is acted on by the verb; the person or thing performing the action of the verb isn't always specified. An example of a sentence in the passive voice is "The car was bought by Sandi" (El coche fue comprado por Sandi). In both languages, a past participle ("bought" and comprado) is used to form the passive voice.
It is important to note that, while common in English, the passive voice is seldom used in Spanish. A common reason for using the passive voice is to avoid stating who or what is performing the action of a verb. In Spanish, that same goal can be accomplished by using verbs reflexively.
