:D I trust you! I trust you! (Yeah I found a /ð/ vs /d/ post that gave me a headache just trying to figure it out.)

My question would be why the lower case in what I assume were manuscripts when even the slightly blasphemous Och Dduw! employs an upper case letter because it seems to be the one and only to which it is referring?

The God of caps has no other gods in his sphere, so there is no need to call him the "best god" - he has no competition. (It would be more appropriate for Zeus it would seem.) But these written references seem to consistently use the lower case and I assume they are religious. What up wit dat?

In the all the older online dictionaries I found upper consistently meant the one and only and lower meant a lesser deity or idolatry. But I hardly did an an exhaustive search. Farking fascinating stuff! Thanks to you and Mike for helping me understand it a tiny little bit.

Could the absence of a capital D be significant of no more than the fact that this is a compound word?

Waaaaayyyy off topic, but those interested in profanity/blasphemy might enjoy this article on how it's done in Quebec. I found it fascinating on several levels. [Edited to say: there's also an informative Wikipedia article on the sacres phenomenon. And I'll repeat that this has almost nothing to do with the original post.]
