Variant TSUs with a thwarted development
Morphological description: Non-time-delimited unit made up of two repeated phases. The first is an articulate shape, relatively short. The second is the opposite of the first (mass, dynam- ics, homogeneity). The reiteration of the two phases is not strict: there is at least one parameter that varies.
Semantic description: It is like something trying to start. Reiteration suggests a repeated effort to reach a goal.
