Capital letters versus not
I'm not quite understanding when to use capital letters and when not to.
It seems like sometimes I see "su" and sometimes I see "Su." I feel like I've also seen "IH" and sometimes "iH."
May I get some help?
Duolingo has a problem in that it recapitalizes multiple choice questions. Most letters in Klingon only appear either lower case or upper care, but not both. The couple of letters that do appear in both cases mean different things in the two different cases. The fact that Duolingo accepts all the letters in either case and sometimes recapitalizes is a big problem for the Klingon course.
The Klingon letters are:
a b ch D e gh H I j l m n ng o p q Q r S t tlh u v w y '
Note that there are two separate letters q and Q that have two different pronunciations and a word can completely change meaning depending on which is used.
Also note that as an independent letter H is always upper case. The lower case version is only used in the digraphs ch and gh and in the trigraph tlh.
Please also note that the digraph ng is considered a single consonant in Klingon and that the ' counts as a full consonant of the alphabet and so is required to be placed properly for correct spelling.
All other letters appear only in lower case (a b e j l m n o p r t u v w y) or only in upper case (D I S). In properly written Klingon there is no such thing as "su" or "iH". Though I think duolingo is unlikely to show you that later one and much more likely to show you something like "'Ih".
