Assuming that early Verdurian typewriters shared the same limitations of their Terrestrial equivalents, I would guess that keyboard design would try to strike a balance between user-friendliness, having the most frequent letters the easiest to access; and functionality, keeping those letters commonly used consecutively on opposite sides of the keyboard to reduce the likelihood of a jam.
So, thinking about it: the Verdurian alphabet has 27 letters. Let's assume that uestu hands work like human ones, and extension is a more comfortable movement for fingers than flexion: this suggests that an optimal layout will have three rows, with the top row containing the most letters. 10-9-8 should work well.
Using the Verdurian version of
Effect/Countereffect as a corpus, let's look at frequencies (ignoring the distinction between vowels with and without a vuáë for the moment - unlike the lenge, this doesn't distinguish phonemes). Interestingly,
ë is far more frequent than either
ü,
ä or
ö (which are the least frequent in the corpus, along with
h), which would argue for it having its own key, but against
ü,
ä or
ö having theirs
In Terrestrial keyboards, the most frequent letters are found towards the middle and the top of the keyboard. The twelve most frequent letters in Verdurian are
e a i n o r u s l m t c (in that order), so let's put them in the centre of the top and middle rows:
? | E | A | I | N | O | R | U | S | ? |
? | ? | ? | L | M | T | C | ? | ? |
? | ? | ? | ? | ? | ? | ? | ? | ? |
Now to fill in around the sides, with frequency decreasing the further towards the periphery we go. Assuming that most uesti are right handed, the right side of the bottom row would be the most accessible after the centre of the other two rows (that's why QWERTY has NM and the most common punctuation where it does) - so the next most frequent letters
d and
š can go there:
Y | E | A | I | N | O | R | U | S | K |
Č | Z | P | L | M | T | C | Ë | V |
Ď | H | Ř | F | B | Ž | D | Š | G |
Let's take the twenty-two most common bigrams in the sample:
an ne re so er le el ra om ce ro et es sa ur la pr ei li ec ta řo. The first thing this suggests to me is that
n should be further away from
e and
a that it is. Let's swap it with
s:
Y | E | A | I | S | O | R | U | N | K |
Č | Z | P | L | M | T | C | Ë | V |
Ď | H | Ř | F | B | Ž | D | Š | G |
Turns out this is not as useful as one might have expected, because it puts
s and
o next to each other, and this is a very common bigram. So let's swap
s and
c:
Y | E | A | I | C | O | R | U | N | K |
Č | Z | P | L | M | T | S | Ë | V |
Ď | H | Ř | F | B | Ž | D | Š | G |
What about the diacritics (except for
ë)? Let's assume that they'll be deadkeys. If we take
ë out of the equation, by far the most common diacritic is the vuáë - let's stick it on the home row, to the right so it's easily accessible. So that a typist doesn't hit the lenge key by mistake when they actually want a vuáë, let's put the lenge on the opposite side of the board, on the bottom row:
Y | E | A | I | C | O | R | U | N | K |
Č | Z | P | L | M | T | S | Ë | V | ◌́ |
◌̈ | Ď | H | Ř | F | B | Ž | D | Š | G |
Just my suggestion of what an keyboard might look like in Verduria.
h/t cedh for
the Frequentizer, which made this quick and easy. BTW, in the Verdurian version of
Subrel i aksubrel, what should be
Á is actually
å.
