Questions & Answers about Hay un montón de libros en la mesa.
Is 'un montón de' an adverb of quantity like 'bastante' or 'demasiado'?
Not technically—it's a noun phrase that literally means 'a pile of' or 'a heap of'. However, in everyday Spanish, it functions as a very common expression of quantity meaning 'a lot of' or 'a bunch of'. You will hear it used all the time instead of muchos (many) or mucho (a lot).
Because 'libros' is plural, shouldn't 'un montón' also be plural?
No, because un montón acts as a single group, just like saying 'a bunch' or 'a pile' in English. You use the singular un montón, add the preposition de (of), and then follow it with the plural noun (libros).
I learned that 'en' means 'in'. Why does it translate to 'on' here?
The Spanish preposition en is very flexible and can mean 'in', 'on', or 'at' depending on the context. Since books are placed on the surface of a table rather than inside it, context tells us that en la mesa means 'on the table'.
Since there are multiple books, why don't we use a plural form of 'hay'?
