Datapoint Principense/Suppletion according to tense and aspect

Txinha (past form of tê 'have') and tava/era (past form of the copula sa) are the only cases of strong suppletion according to tense. Instead of txinha, tava tê may also be used. This construction follows the regular pattern.
Têvê vs. Ø tê 'had (PFV)' and txinha 'had (IPFV)' is the only case of strong suppletion according to aspect; the form têvê is extremely rare.
