a system where a same-subject - reference tracking construction uses a deranking strategy, whereas the different-subject reference tracking construction uses a balanced strategy. Example: Wolof dem na ma à o ko 'I went and called him' [same-subject] uses a Serial Marker à and a deranked Subjunctive verb form o; nyeu on na te wakh on na ma ko 'He came and I told (it to) him' uses the balanced construction with the simple verb form, the Past Tense on and the Indicative Marker na.
