 However, exceptions to the gradual diachronic process have been observed where the deflexion process diminished or came to a halt, or where inflexional case marking was occasionally reinforced.There are also a few cases of reversed directionality, e.g.in the evolution of the common Romance inflected future and conditional (or "indicative future-of-the-past") from earlier periphrastic suppletive forms for the loss of the corresponding classical Latin tenses.
