The verb in Ao is defined as a
morpheme capable of taking tense/aspect markers or the
imperative markers. The verbs in Ao are not marked for
person-number-gender.
4.1. The
Structure of the Verb :
The structure of a simple verb in Ao may be defined as follows :
(i) Root
(ii) Prefix + Root
(iii) Root + Suffix
(iv) Prefix + Root + Suffix
In the verbs which have a prefix, the prefix may be either the
classificatory prefix /a/ and /me/ or the negative indicative
prefix /ma/ (which becomes /me/ in certain contexts) and the
negative imperative prefix /ta/ which becomes /te/ in certain
contexts). The classificatory prefix /a/ ‘which is very common’
occurs with most verbs and it is difficult to fix a meaning for
it. The prefix /me/, which occurs with a few verbs of action
which require some physical or body force. It may be mentioned
that the classificatory prefix /a/ is dropped in some contexts
(cf. 1.7.). However, the classificatory prefix /me/ is not
dropped.

When a verb has a suffix, the suffix may beeither an aspect
marker or tense marker or the imperative marker. If there is
an aspect marker and a tense marker as in the case of the durative
constructions the tense marker is added to the auxiliary verb
which follows the aspect marker.
