Judging from the information in your post, I recognize that you are a very wise person, jan Kipo. But why must you go around correcting my perfectly good tp sentences? Yes, my sentence was ambiguous. But I'm an ambiguous person. tp is an ambiguous language. It's not like I learned tp yesterday, either. I've been using it frequently for the past two years going on my third. I think you can hardly call me incompetent unless I rush what I'm typing. I think I don't need corrections on every corner.
^The above was me getting worked up over nothing. Symptoms can include nastiness, rudeness, sarcasm, and other minor maladies. So please, don't take it to heart; it just annoys me when people correct me all the time.
Loewe is German. It is written, obviously, "löwe". It is pronounced [lœvə] in Standard High German. Now, since I don't like the spelling Lewa (which is the closest in pronunciation in terms of vowel height and other phonological characteristics) or 'Soweliwawa' as you suggested (I tried it before posting my original post; didn't work), I chose "Lowe" to share because the spelling corresponded well and it seemed to me more euphonic (my spell-checker says that's not a word... it lies) than any other possibility.
I still prefer loewe to anything else, though.
