Male viera confusing naming conventions for veena

[Liamont]

In the mountainous region inhabited by the Veena, villages are frequently enveloped by heavy snows. A male Veena’s surname marks him an integral, albeit small, part of this landscape, combining references to snow crystals with the word “wesfv”─“guardian.” However, as the snowflake-based themes employed and the number of surnames in use differ from village to village, the examples below should be considered only a small sampling of the possibilities.
Unlike the Rava, the Veena are not known to regard their Wood-warders as sharing any particular affinities or bonds due to their surnames.

Male Veena surnames include:
Sjadarwesfv (“Needle”)
Jgnewesfv (“Sheath”)
Monnawesfv (“Prism”)
Huorlwesfv (“Shield” – referring to what naturalists term “plates”)
Ornedwesfv (“Fan” – referring to “sectored” plates)
Qufiswesfv (“Bullet”)
Foixewesfv (“Spear”)
Ubmuawesfv (“Wand” – referring to gohei twins)
Copihwesfv (“Branch” – referring to dendrites)
Rawbewesfv (“Bone” – referring to hollow crystals)
Phiitehwesfv (“Seagull”)
Gahjewesfv (“Rime”)

Can this be clarified a bit more? How does "bullet" or "spear" or "seagull" refer to snowflakes? Or does it mean that those are examples where their surnames do not need to have relation to snowflakes?
