Help translating よなも in a song


This is from a Trigun soundtrack, song called Sound Life
([lyrics](http://www.animelyrics.com/anime/trigun/trisl.htm)), 3rd line:

> ３つ目の夜に ワルツの子は **世界面** にウエーブを 打つ

The 世界面 is translated as "world face", however pronunciation is given as よなも.
I can't find translation for this よなも anywhere. I have listened to the song as
well and to my untrained ear it does sound like よなも
([YouTube](http://m.youtube.com/watch?v=5EQHg_bhCKY)).

The Animelyrics site translates the whole thing as "children of the waltz make
ripples on the face of the world" which I believe ignores ウエーブ. On another
site it was translated as "children of the waltz name it Uebu" which makes use
of ウエーブ and I believe translates よなも as name (名？), however the same word
appears in the 5th line and there "name" does not make sense.

I know that sometimes poetry and songs deviate from standard language so it
might be the case?




I believe よなも is 世な面, meaning roughly "the surface of the world". Here's how
it breaks down:

  * よ is 世 (world)
  * な is the archaic case particle な, which is the same as the modern particle の
  * も is 面 (surface), a word derived from おも (the お is elided)

The case particle な is rare in modern Japanese. It's preserved in several
words:

  * 眼（まなこ＝[目]{ま}な[子]{こ}, meaning 目の子）
  * 港（みなと＝[水]{み}な[門]{と}, meaning 水の門）
  * 水面（みなも＝[水]{み}(な)[面]{も}, meaning 水の面, where な is unwritten）

What all these words have in common is that they were formed back when な was
in common use. I'm not sure whether よなも is a historically attested word or
not, but if it's not, it was probably formed on the pattern of these words--
particularly 水面 as pointed out by @Flaw's comment, fitting the imagery of
ウエーブ.
