There are many words in Spanish that are distinguished only by the position of the stress. In fact it is very common for verbs, for example: - Cálculo: "calculation" - Calculo: "I calculate" - Calculó: "he calculated" Having said that, the standard collation rules are: - First, unmarked vowels. - Second, vowels with an acute accent. - Last, vowels with diaeresis (the diaeresis is very rare and in native words only appears in the syllables "güe" and "güi", were it means that the U should be pronounced, as otherwise it would be silent).
