In verb conjugation, noun declension, and other word formation processes, stress shifts can occur. Verbs can have homographic forms only distinguished by stress, such as in "el suflă" which can mean 'he blows' ("el súflă") or 'he blew' ("el suflắ") depending on whether the stress is on the first or the second syllable, respectively. Changing the grammatical category of a word can lead to similar word pairs, such as the verb "a albí" ('to whiten') compared to the adjective "álbi" ('white', masc. pl.). Stress in Romanian verbs can normally be predicted by comparing tenses with similar verbs in Spanish, which does indicate stress in writing.
