Two general principles can be stated which govern the relative order of a cluster of adverbials in a sentence. They are: The PTS and SP. The two principles apply to the relative order of adverbials whether within a class or between classes. The general guideline can be roughly stated as follows:
A. The relative order of adverbials can be changed to suit the demand of information focus.
B. The PTS and SP jointly function as general guidelines that condition the ordering of multiple adverbials. Generally, multi-classes of adverbials occur in the following ordering sequence:
‘time adverbial – positional adverbial – adverbial of modality – subject adverbial – adverbial of source or direction – manner adverbial + V’
(The positions of the last three kinds of adverbial are interchangeable).
