Spanish adjectives are generally postpositive, that is, they come after the noun they modify. Thus "el libro largo" ("the long book"), "la casa grande" ("the big house"), "los hombres altos" ("the tall men"), etc. There are, however, a small number of adjectives, including all ordinal numerals as well as words such as "otro" ("other") and "todo" ("all"), that must be placed before the noun they modify. There are also a small number that can be placed both before and after the noun and that change meaning according to that positioning, and some adjectives, especially those that form something of a fixed phrase with the noun (e.g. "oscura noche" ("dark night"), "alta montaña" ("high mountain")), can be placed before or after the noun with little change in meaning.
