Detail #380: A New Spot For Alignment

I recently came across this, a post whose content I am not really going to comment (due to the feeling that I don't know enough about this particular topic.) However, it sparked an idea in my mind:

Why not make an alignment-like system with regards to symmetrical vs. reciprocal actions? Some verbs could imaginably only take one or the other type, and here we could get an interesting set of situations:

• verbs that are exclusively symmetrical
• verbs that are exclusively reciprocal
• verbs that can be either one or the other

Let's use s and r for arguments of exclusively s/r verbs, and S and R for verbs that can take one or the other. The way any particular marking works may differ from the way others are marked: reciprocal pronouns with differential object marking distinguishing different meanings, verbal affixes, particles, auxiliaries, adverbs, etc.
Potential solutions:

Trivial bipartite:
s = S
r = R

Asymmetrical bipartite:
s = S = r
R

or

S
s = R = r

Unhelpful bipartite (unlikely)
s = r
S = R

Tripartite I
s = r
S
R

Tripartite II
s = S
r
R

or

r = R
s
S

Diagonal Tripartite (unlikely)
s = R
r
S

or

S = r
R
s

Unhelpful Tripartite (unlikely)
s
r
S = R

Quadripartite (unlikely)
s S
r R

One thing that feels realistic, though, is that for some verbs, you may also have occasional exceptions like so:

Exceptional Marking I

S' = R
R' = other way that coincides with some other thing in the language?

The ' there marks that these are exceptionally marked ones, and that the "R" on the right hand of the equals mark stands for the marking, not the meaning.

Detail #6: Split dechticaetiativity

In this constructed language sketch, certain pronouns and nouns follow a dechticaetiative pattern while some follow a normal accusative-dative pattern.

Pronouns that would follow the dechticaetiative pattern could include reflexive pronouns and 1st and 2nd person pronouns in general. This way, reflexive pronouns would only be distinct from normal third person pronouns by the presence of a different case and slightly different morphosyntax in certain situations.

Since it's late in the evening, and this idea occurred to me just now,  I figured I might just as well jot this down and elaborate on what this means and how it could work in later posts. For the readers that do not know what dechicaetiative is, I guess I will explain that in the next post.
