Relative clauses - 2nd attempt

I apologize for the previous imprecision.
There are two questions in this message & I seem to have gottent
them mixed up!

Question #1---

The verb in Senjecas is marked only for mood:
-a = indicative,
-o = subjuncive,
-e = imperative.

I want to indicate a relative clause by a marked verb; there are no
relative pronouns or adverbs in Senjecas.  I want to indicate this
with a -u ending on the verb.  The language is SOV so the relative
clause would precede its noun.

The man who is standing is my father.

n-us-ë sâât-u µîr-us m-úsïo âp-as ês-a.

3person-Class6.NOM.sg-EP(ENTHETIC)
stand-REL(ATIVE)
man-Class6.NOM.sg
1person-STATIVE.sg
father-NOM.sg
be-IND

Question #1: Can I call this the relative mood?

Question #2---

Without a definite article a sentence in the indicative mood could
be either general or specific.  E.g.:

nib-êes óós-vi µêrs-a

cheetah-Class3.NOM.pl
swift-ADV
run-IND

That could mean either "The cheetahs run swiftly" (some specific
cheetahs I am watching) or "Cheetahs run swiftly" (all cheetahs).

I want to use the preposed particle (not prefix) _im_ to mark the
generic meaning.  Thus:

nib-êes óós-v-' im µêrs-a could only mean "cheetahs run swiftly."

cheetah-Class3.NOM.pl
swift-ADV-EL(ISION)
GPTC (GENERIC PARTICLE)
run-IND

Question #2: Is this structure known as generic mood or generic
aspect or generic something else?

I hope this clarifies my previous muddled attempt.
