This paper seeks to examine the status of verbs of movement in Moroccan Arabic (MA) as well as the forms yemken and yeqDer. Generally speaking, these expressions have failed to obey the laws governing the use of auxiliaries. These verb forms will be studied in relation to their polysemous aspect. It is only when there is a second meaning that the relation of auxiliation2 might be said to occur. Furthermore, some instances within this verb subclass involving the imperative mode are considered as semi-auxiliaries3. As far as the forms yemken and yeqDer are concerned, they have achieved an advanced level to become frozen structures.
