You make a
very good point about the proper modifiers. That means I don't need to worry about making them cross the previous word to capitalize them!
(if the word begins with jo or ju.) Except with Jo, we would need to cross that to show it was proper and not just 'jo'; I think for consistencies sake we might just say to cross and disjoint all proper nouns.
I just had a eureka moment; if we say all proper nouns must be disconnected from the word that follows then, unambiguously, we would resolve the case of word-internal jo/ju.
I will get to the writing and scanning of people's names tomorrow. Keep in mind the ultracursive mode is more calligraphy than shorthand anyways, and it's only there because phrasing is a real issue that Gregg shorthand tackles for English and there are so many cut-and-dried phrases in tp, or at least there seem to be, that I thought an analogous solution would be at least theoretically desirable. I don't really think anyone will write out whole connected sentences. The memory load of keeping a sentence in mind would probably harm execution.
I have gone back to the drawing boards, I think I'll probably borrow symbols from one of the Japanese shorthands. It should be easier to write than Gregg but would still follow it's writing direction.
As for your own writing, in reality, if you can read it that's good enough. Even if you get pretty sloppy the quirks and idiosyncracies you introduce into your execution won't matter for this. They might even help you distinguish words! The word outlines are pretty distinctive in my opinion. If you can consistently keep letters distinguished that should be more than enough, even if it is not based on the minimal properties in my own writing ie [+/- curve][+/- ascending] -- for instance, length becomes important in your writing of a letter,
or only in certain words. Some letters can probably even merge without too much hindrance to reading--it's not like tp has a lot of minimal pairs, or even a large lexicon. In English shorthand, I don't think most people who learn Pitman shorthand can read each other's writing.
The real issue is learning to write with a loose hand.
EDIT: Looking at the Juju example I realize that it would not be OK to separate the 2 'ju's, because then, would it be "..Ju jo" or "Juju"? I will have to choose a curved shape for it then so that I can reduplicate without issue (straight lines cannot reduplicate because [+/- length] is not a distinguished attribute within the system; now two curves together on the other hand are always distinguishable and resolvable).
EDIT2: I also just realized that it will be difficult to make ju work as a connector with words that begin in vowels because they will attach to the 'j-'. ja/je happens enough inside words to make these potentially confusing strings. Even if they're uniquely parseable it's something of a wall of text. Nevermind how to work -n/w-/u- into the picture.
I'm taking suggestions.
so remove it
