In many present tense forms, the 'o' changes to 'ue', such as in the third person singular present tense where the reflexive pronoun 'se' is placed before the conjugated verb to form se duerme (he/she goes to sleep). In the preterite past tense, the 'o' changes to 'u', resulting in the form se durmió (he/she fell asleep).
