2.  Time and Moods:  A subjunctive is formed by ana if, when, followed by the particle ka, or by the use of saea.

Conditional affirmation is expressed by saumala.

The illatives are fi and fe, and mean, then, in that case, following upon, just now, for the first time:  ta ka fi uri then said he, gami mifi saitamana na tala uta and how shall we know the way?

Fe as an illative denotes, in that case, following upon; fe is also used like ha’i in Sa’a, to denote repetition or continuance or restoration:  na abana e fe boeboela lau his hand was restored whole again, gera ka fe dao toona they will certainly reach him, daro fe lea lau go they went on again, da tefe bae ana tesi baela they all cried out together.

Na is used following the verb to form a preterit:  nia mae na he is dead.  Finality is shown by the use of sui:  sui na it is all finished, nia kafi dao sui na when he shall have arrived, sui nana it is finished, sui ta thereupon, after that.

For the imperative the simple verb is used:  o lea amu go away; fasi may be added for politeness:  lea fasi amu you go!

3.  Negative Particles:  The foregoing particles are not used in negative sentences.  The negative particles are langi, e langi, si.  These may be combined:  nia langi si saea he does not know it, e langi mu si rongoa ma e langi mu si saea you have neither heard it nor seen it, e langi nau gu si lea I am not going, e langi uri ta ai e adasia no one has seen it, e langi asia not at all.  The verbal particle ka may be used in negative sentences with the addition of si, kasi bobola it is not fitting.  The dehortative and the negative imperative is fasia:  fasia oko lea do not go! fasia gera ka adasia let them not see it, o fasia oko luia do not forbid it.

Genitives:  ni, i are used to express purpose.

4.  Suffixes to verbs:  There are certain terminations which, when added to neuter verbs or to verbs active only in a general way, make them definitely transitive or determine their action upon some object.  These are of two forms: 

a.  A consonant with i:  fi, li, mi, ni, ngi, si, or i by itself; e.g. tau, taufi; mae, maeli:  ano, anomi; mou, mouni; sau, saungi; ada, adasi; manatat, manatai; to the verb taa to be bad, both si and li are added and the causative fa is prefixed:  fataasi, fataali, to make worse.  Certain verbs which are active in Lau are neuter in Sa’a:  angai to lift, angaia lift it, Sa’a angainia; faodo to straighten, faodoa straighten it, Sa’a ha’aodohie; famae to kill, famaea, Sa’a ha’amaesie; famou to frighten, famoua, Sa’a _ ha’ama’usie_.
