the verb is =personal=, and this accounts for its being in the plural. In "me bastan diez libras," "diez libras" is the subject.
The verb is impersonal when referring to a whole statement, as—
(Ello) es necesario: It is necessary.
Of Haber and Hacer as impersonal verbs, we have treated in Lesson
VIII and Lesson XVI.
We add here that Hacer is used impersonally before certain nouns to denote the state of the weather or of the temperature, as—
Hace calor, frío, lluvia, viento, sol, etc.: It is warm, cold, rainy, windy, sunny, etc.
Valer used impersonally = "to be better," as—
Más vale así: It is better so.
Expressions like "¿Qué se dirá?" or "¿qué dirán?" (What will people say?) may also be called impersonal uses of the verb.
