Why not Dal'thori

Thori'dal, not Dal'thori... I was wondering why... Dal'thori - Fury of the Star... But wait, it's Stars' Fury, where dal should be in plural.
Could it be that the plural makes the order different? I guess it's the case in Thalassian.

thori - fury
dal (kal in Darnassian) - star, also mage

noun1'noun2 translated as:
- 'noun2 to noun1' (noun1: thori, noun2: dal) if noun1 is singular
- 'noun1:s' noun2' (noun1: dal, noun2: thori) if noun1 is plural
