Hi!
The other day, I was thinking, "wouldn't it be useful to have a
sumti-raising infix cmavo?".
In other words, wouldn't it be useful to have a cmavo that goes between
the raised sumti and the rest.
la solpa'i / la selpa'i / la me zi'o already discussed it over on his blog:
http://selpahi.weebly.com/lojban/proprietor-fronting
Having said that, there is this fancy word, {zo'ei} (of LAhE).
It's roughly equivalent to {zo'e pe}, but more of a single word than two.
While {tu'a}, {jai} and {kai'a} (from the blog post) relate to a sumti
and an event,
{zo'ei} is a relation between a sumti and something related to it.
This brings us to metonyms.
Metonyms are somewhat related to metaphors;
they are the usage of an object in a sentence instead of something of
that object.
For example, in the sentence "Orders came in from the office", even
though "office" really stands for "boss" (or something), "office" is
used because it has some relation to "boss".
If we were to translate this sentence to Lojban with the metonym usage,
we'd get
{ lo briju cu minde }.
Because Lojban is a logical language to some extent, it's incorrect to
say that -- offices don't give orders.
Just like { mi cizra }, which needs a {jai} (because I'm not an event),
{ lo briju cu minde } should also be fixed with a {jai}-like cmavo, X.
X, contrary to {jai}, would be in SE (because we don't need to use the
{jai}-plus-sumtcita feature).
In order to fix the example, we'd say {zo'ei lo briju cu minde} (which
is not very natural), or, using X, {lo briju cu X minde}.
Explaining it with a simple relation might help:
tu'a : jai : (kai'a) ::
zoi'e : X : Y
It's also worth considering the Y, because it could be useful.
