Wordlist passed our unit test in python-mnemonic. I especially like that words don’t use diacritic. ACK for me.

Is “nynfa” Czech word? orchest? peleton?

zizelevak commented at 7:19 am on January 31, 2017: contributor

@paveljanik thanx, you found two mistakes. Correct forms are “nymfa” and “orchestr”. I fixed both mistakes. Peleton is OK, according Institute of the Czech Language http://ssjc.ujc.cas.cz/

paveljanik commented at 7:25 am on January 31, 2017: contributor

@zizelevak Check http://prirucka.ujc.cas.cz

zizelevak commented at 7:34 am on January 31, 2017: contributor

@paveljanik We both use databases from Institute of the Czech Language. You use only handbook, I use Dictionary of written languages, my database is more complex. Meaning of peleton: The peloton (from French, originally meaning ‘platoon’) is the main group or pack of riders in a road bicycle race. Edit: I explain peleton (older version of this post was explaining nymfa)

xHire commented at 7:41 am on January 31, 2017: none

@zizelevak More complex may not be always correct, see yourself: http://prirucka.ujc.cas.cz/?slovo=peloton – even referenced SSJČ states that “peleton” is incorrect form. By the way, Prirucka is currently the best normative reference available.

zizelevak commented at 10:45 pm on February 10, 2017: contributor

@paveljanik

changed bariera –> smaragd

ch after c? - worldlist is sorted by english alphabet, not by czech alphabet. Its simpler for implementation this wordlist in wallet software.

Limit - it is not possible use, its included in english worldlist mince - it is not possible use, its included in french worldlist

“Motivace” - I think its more suitable than “motiv” Both words have foreign orgin, but “motivace” has czech suffix -ace.

motor - it is not possible use, its included in english worldlist

“moudro” - I dont agree. “Modrost” is 50-times more frequent than “moudro” according czech corpus SYN2005

nikl - its OK its metal, chemical element with atomic number 28

norma - it is not possible use, its included in spain worldlist

changed Novotvar –> novota

“odolat” - it is not possible, its simular to other word in wordlist “odvolat”

“okov” - Its part of well, “Okovy” it is shackles, I prefer Okovy, I think its more common

changed otrhanec –> otrhat

“popis” - it is not possible, its simular to other word in wordlist “dopis” “robot” - it is not possible use, its included in english worldlist “tank” - it is not possible use, its included in english worldlist

@zizelevak Thanks for updates! Can you now please squash?

I’m fine with the list now. Great work, BTW! 👍

xHire commented at 7:33 am on February 11, 2017: none

Ah, thanks for reminder (via notification), I also had some comments/questions, will post them later today (probably in the evening)! :c)

xHire commented at 8:57 pm on February 11, 2017: none

I divide my comment into several groups to make it easier to work with. One thing to write first: while I make comments about some words, at the end I also provide a buffer of alternatives just in case it is unclear with what words potentially replace some of those problematic ones. (By the way, comments at the beginning of each section are mostly for non-Czech speaking followers.)

Lhota (spelled as a name)

Infrequently used/known words

In this list I include also (not only) words that I have never heard of. :c) It doesn’t mean I can’t just look them up, but I suppose they are so rare that they might not be so good to be in this dictionary.

falzum
gondola
karfiol
luneta
nefrit
nestor
normativ
opuka
pagoda
ponton
rytec
sahel
sutana

Words with different diacritics

There are some words in Czech that have dual spelling—one time without diacritics, other time with diacritics. Those I list below sound to me quite forced.

chlor
chrom
folklor
globus
kasino
kastrol
lahev
mixer → mixovat
naftalen → nafta (but it’s probably already taken in another dictionary I suppose)
ozon
tampon
vitamin → vitalita

Plural forms

As stated in README, words should be in their base forms which means they should be in singular.

holinky → holinka
lenilky → lentilka
piliny → pilina

Words with (optional) spacing

So called „příslovečné spřežky“—words which are allowed to have their preposition transformed into prefix. Below are those I suppose are not so much more common in a single word form or might be confusing or don’t sound so well to me.

nadlouho
nadrobno
natrvalo
natvrdo
navenek
zdaleka

Miner modification proposals

So as to make some words sound more natural or clearer.

dominant → dominanta
hltan → hltat
kmit → kmitat
logicky → logika
mulat → mula
muzika → muzikant
naposled → naposledy
pasivum → pasivita
roup → roupice
vespod → vespodu

Forced forms of words

Technically correct, but (mostly) uncommon word forms (forced into these just to make them lose their diacritics).

drtivost
kalnost
(kluzkost)
(ladnost)
levnost
mokrost → mokro
movitost
suknice → sukno (suknice is really so old ;c))

More like informal forms and/or not sounding neutral

(I know some are (probably) correct, they just don’t sound ideal to me.)

fabrika
fanda
fara → farnost
fiflena
fixa → fixace
glejt
hafan
hezoun
kafe
machr
marodka
mejdan
nimrod
piksla
smola
spratek
(tatarka)
vatra
vloni → vloha
(zrzek)

Words I simply don’t like here ;c)

(Or I couldn’t decide in which other group to put them.)

euro (not a Czech word and might also become deprecated soon)
flirt → flamendr
lepra
(limitace)
minibar → miniatura/minimalista (just wow, why to choose the word “minibar” among all those words prefixed with mini- :-D)
(mocensky)
nahota → nahodile/nahoru
nevina
(oktet)
onkolog
podle (more often is a preposition IMO)
sekvoje (because it’s commonly spelled a tiny bit differently)
sklivec
tankista → tanker (if not already used elsewhere)
tavenina → tavidlo
tenor → teror/terorista
tunika
varan

Alternatives

I counted 64 words without a suggestion in the upper lists. The words below are already checked not to collide on prefix level and many also on a single letter difference level. I have 58 of them which is 6 words short… So I put 6 or so words above into parentheses to indicate their lower priority. ;c)

borka
celistvost
deflace
destilace
dioda
displej
epopej
firma
fukar
holokaust
horda
kabriolet
kapybara
klima/klimatizace
kosmonaut
kotoul
kotrmelec
kropit/tropit
lamela
litr
lodivod
lokomotiva
loterie
mela/melasa
mydlinky
nanometr
nektarinka
nora
nutrie
orangutan
parabola
peloton
periskop
pikolitr
ponynka
prahora (prahory? in this case, I’m tending to call it a plurale tantum, although it’s (strictly speaking) not the case)
pranostika
pruh/prut
rakovina
relevance
rotoped
rydlo
seschnout
sinusoida
spokojenost
stranou
surikata
tempo
tiskopis
titrace
tranzistor
traverza
trend
utiskovat
vodivost
vyrvat
ziskovost
zkontrolovat/zkonfiskovat
zmutovat

I’m looking forward to hear your opinion! :c)

What’s the status of this?

zizelevak commented at 6:53 am on March 6, 2017: contributor

@luke-jr Orginal wordlist was checked by @slush0 and passed all tests. Some members adviced changing some words, which were problematic from language reasons. I dealt with all requests. I think that actual worldlist should be checked by @slush0 again (I am sure that will passed his tests, because I made own tests) and its ready for publish

paveljanik commented at 7:30 am on March 6, 2017: contributor

@zizelevak what about aspirace and kapybara?

zizelevak commented at 7:41 am on March 6, 2017: contributor

@paveljanik In czech frequency corpus: aspirace has frequency 433 points, kapybara has 16 points. Aspirace is quite common czech word. Kapybara is not much frequent, but we have there tens of words with less frequency than kapybara. I will keep both words in list.

zizelevak commented at 1:37 pm on July 14, 2017: contributor

@luke-jr I think that this version is finnal.

luke-jr commented at 5:18 am on July 26, 2017: member

@slush0 Can you re-ACK the changed version?

I have created a Unicode NFKD-normalized and sorted czech.txt from zizelevak/bips@b7f682f, as modified by approximately the following command:

0uconv -f utf-8 -t utf-8 -x '::nfkd;' < czech.txt | \
1	LC_ALL=C LANG=C sort -s > normalized/czech.txt

The result has been confirmed to not have any leading BOM, and to have a final line terminated with '\n' (#622). I did not yet examine the source for these issues. I did examine the source to confirm that no lines had any trailing whitespace (see nym-zone/easyseed@08a05b4, #442).

I’m not sure how this was missed, but the order of words in the wordlist is not alphabetical. The word “svetr” should come after “svazek”.

The fact that the list looks sorted but is not may cause subtle bugs in applications using binary search to look up code words.
