Among the syntactic changes that can be observed in transition from Old Norwegian to Modern are following word order changes: loss of OV order, object shift a VP containing verb (non-finite or any subordinate clause), preverbal preposition, and topicalization bare head. The fact these all seemto occurat same timeis not accidental. was arguably VO language, like Norwegian, but unlike also possib...

Given an infinite word x over an alphabet A, a letter b occurring in x, and a total order σ on A, we call the smallest word with respect to σ starting with b in the shift orbit closure of x an extremal word of x. In this paper we consider the extremal words of morphic words. If x = g(fω(a)) for some morphisms f and g, we give two simple conditions on f and g that guarantees that all extremal wo...
