=C2=A0.e'i is part of a s= eries of illocutionaries e'a/e'e/e'i/e'o/e'u with the s= peaker's attitude towards an action to be performed (typically but not = necessarily) by someone else:

.e'a: I hereby g= rant permission for this to take place:

.e'e: I hereby give e= ncouragement for this to take place:

.e'i: I hereby impart in= structions for this to take place: (or to use "constraint": I her= eby impose a constraint for this to take place:)=C2=A0

.e'o: = I hereby pose a request for this to take place:

.e'u: I hereb= y make a suggestion for this to take place:

.ei is= used to express how one feels the world ought to be:

<= div>.ei: It ought to be the case that this takes place:

So we have:

=C2=A0.ei mi cliva

=C2= =A0It ought to be the case that I leave.

=C2=A0I ought to leave.<= /div>

=C2=A0I should leave.

=C2=A0.e'i mi = cliva

=C2=A0I hereby impart instructions that I leave.

= =C2=A0(Direct first person singular imperative not available in English, bu= t "e'i mi'o cliva" "Let's leave".)

=C2=A0[ju'a] mi bilga lo ka cliva

=C2=A0[I a= ssert that] I am under the obligation of leaving.

=C2=A0I have to= leave.

There are circumstances when all three can= be felicitously used, even though their precise meanings are somewhat diff= erent.

Examples with "mi" as the agent a= re not always the best to show how UIs work, because it makes it harder to = disentangle the effect on "mi" as the speaker from the effect on = "mi" as the agent. With "do" we have:

=C2=A0.ei do cliva

=C2=A0It ought to be the case that you= leave.

=C2=A0You ought to leave.

=C2=A0You should leav= e. (But not because I say so.)

=C2=A0It's best if you leave.<= /div>

=C2=A0.e'i do cliva

=C2=A0I hereby i= mpart instructions that you leave.

=C2=A0You should leave. (Becau= se I say so. An instruction.)

=C2=A0Leave.

=C2=A0[ju'a] do bilga lo ka cliva

=C2=A0[I assert that] Yo= u are under the obligation of leaving.

=C2=A0You have to leave. (= A statement, not an instruction.)

With a third per= son:

=C2=A0.ei la .alis. cu cliva

= =C2=A0It ought to be the case that Alice leaves.

=C2=A0Alice ough= t to leave.

=C2=A0Alice should leave. (But not because I say so.)=

=C2=A0It's best if Alice leaves.

= =C2=A0.e'i la .alis. cu cliva

=C2=A0I hereby impart instructi= ons that Alice leaves.

=C2=A0Alice should leave. (Because I say s= o. An instruction.)

=C2=A0(Let Alice leave.)
