Present and the Past (probably really further divisible) Tenses of the
former, and the Present of the latter. As an example I may give the verb
to strike, of which the root is assumed to be matum = a stroke.

Indicative Present : nudu ngatu : matumeipa = I am striking him.
Indicative Perfect : nudu ngatu : matnmina = I struck him.
Indicative Future : nudu ngatu : matumeipakai = I shall strike him.
Imperative Present : nudu ngidu : matumur = strike him.

Assuming a root to each, I find 94 of the verbs under examination to
agree in having the present tense of the indicative terminating in pa: of
these 70 end in aipa, 14 in ipa, 6 in epa, and 1 in aipa.

The perfect tense (setting aside some inexplicable irregularities)
exhibits a great variety of terminations for the formation of which no
rule can yet be given: these are an, ana, ani; in, ina, ima: em, ema;
eima, eiun; and un.

The future tense alone is perfectly regular; it is simply formed by
adding kai to the present.

The present tense of the imperative mood in those verbs having the
present of the indicative ending in ipa terminates (with one exception in
i) in ir: in the others the terminations of this tense are ur (the most
frequent); ar (the next in order of frequency), ara, ari; ada, eada; e,
eio, eir, erur; and o.

After all I am inclined to suppose that the Kowrarega verb, although
apparently complicated, is of simple construction; and that its various
modifications are caused by the mere addition to its root of various
