Hausa retains the widespread Chadic three-term system of masculine singular, feminine singular, and plural (gender neutral). This is reflected in nominal forms and in agreement patterns. With a few grammatical morphemes, e.g. the Linker (na/ta/na) the masculine singular and the plural share the same marker. Tense–Aspect–Mood (TAM) is generally indicated by an overt marker after the subject pronoun and before the verb. The finaln in the Completive paradigm is not a TAM marker as often said, but rather a plural formative. The marker in the Subjunctive is zero. This form historically also indicated the Aorist, which still occurs but in the negative only. The causative is and was formed syntactically using a main verb sâa ‘to cause’ (lit. ‘to put’) and not by means of a morphological extension on the verb. Indirect objects have changed significantly from Old Hausa, in word order, in the form of the marker(s), and in the specific pronouns used. Verbs in the grade system vary in their pre-indirect object usage. Reflexives are built on the noun ‘head’, the question being whether they originally might have employed ‘body’ instead, which is now found in reciprocals.
