In the first register (in older speakers, in rural areas speakers or in speakers with little exposure to Portuguese) there are only two forms for the verbs: one for the present (ê , stâ , têm , tenê , crê , sabê , podê , devê , mestê ) and one for the past (éra , stába , têmba /tẽ, tenêba , crêba , sabêba , podêba , devêba , mestêba ). However, on the contrary of regular verbs, when the base form is used alone it represents the imperfective aspect and not the perfective aspect. Therefore, mí ê, m' têm, m' crê, m' sabê mean "I am, I have, I want, I know", and not "I've been, I've had, I've wanted, I've known", as it would be expected. Parallelly, mí éra, m' têmba, m' crêba, m' sabêba mean "I was, I had, I wanted, I knew", and not "I had been, I had had, I had wanted, I had known", as would be expected.
