In the shop: shoe sizes, light colours and the till (el número, claro, la caja)

Same word, a new meaning in the shop

You already know four of these words. In a shop they usually mean something else.

Shoe sizes and light colours

In Spain, clothes come in a talla and shoes usually in a número.

After a colour, claro means light and oscuro means dark. The pair usually stays the same with any noun: una camisa azul claro.

Prices: per kilo, per night

After a price, por + a noun with no article usually means per: por kilo, por hora, por noche. You will also hear dos euros el kilo, with the article and no por; it means the same.

The till, the only one, and lower

In a shop, la caja is usually the checkout where you pay. Anywhere else it is usually a box.

Before its noun, after el or la, único usually means the only: la única tienda, el único vestido rojo.

With a thing as its object (prices, the music, a coat on a shelf), bajar usually means to lower, turn down or take down. Bajar la escalera is still to go down the stairs.
