Expressing "Enough"
To say you have "enough" of something, use the word suficiente. When placed before a noun to describe a quantity, it must agree in number (singular or plural) with that noun, but it does not change for gender.
| There is enough merchandise in the inventory. | Hay suficiente mercancía en el inventario. |
| You store enough products in that aisle. | Almacenáis suficientes productos en ese pasillo. |
Expressing "Too Much" or "Too Many"
To express "too much" or "too many", use demasiado. When modifying a noun, it must agree in both gender (-o/-a) and number (-os/-as) with the item you are describing.
| We lack milk because there is too much demand. | Nos falta leche porque hay demasiada demanda. |
| Too many products are missing from our inventory. | Faltan demasiados productos en nuestro inventario. |
Dropping the Noun
If the item you are talking about is already obvious from the context, you can leave the noun out entirely. When standing alone, suficiente(s) and demasiado/a/os/as still match the gender and number of the hidden noun they replace.
| We have too many boxes; there are already enough. | Tenemos demasiadas cajas; ya hay suficientes. |
| We have enough boxes in the inventory, today too many are left over. | Tenemos suficientes cajas en el inventario, hoy sobran demasiadas. |
Modifying Verbs and Adjectives
Sometimes, "too much" describes an action (like ordering too much) or simply means "too" before an adjective (like being too small or too serious).
When demasiado modifies a verb or an adjective instead of a noun, it acts as an adverb. Adverbs never change their form, so it will always stay exactly as demasiado, regardless of who or what is involved in the sentence.
| The customers order too much; it is impossible to store everything. | Los clientes piden demasiado; es imposible almacenarlo todo. |
| The coffee shortage is an overly serious problem. | La escasez de café es un problema demasiado grave. |
Hardly any: apenas
Apenas means hardly, barely: almost nothing, or almost not at all. It usually goes before the verb, and then needs no no.
