Reduplication and words form


Does 態々 derived from 態と? And does 態と derived from waza 「業 」and case-marking
particle 「と」?




**In modern Japanese** , わざわざ and わざと are different adverbs. わざわざ mainly means
"to bother to do ～ (although it's not necessary); to take the trouble to do ～;
all the way; specially", whereas わざと means "do ～ on purpose (knowing it's
usually a bad thing to do it); intentionally for a reason". But わざわざ sometimes
means "intentionally", and in this case the two are interchangeable (e.g.
"わざわざ/わざと聞こえるように悪口を言う").

**In archaic Japanese** , according to [a
古語辞典](https://kobun.weblio.jp/content/%E3%82%8F%E3%81%96%E3%81%A8) and [this
article](http://www.urayasu.meikai.ac.jp/japanese/meikainihongo/8/sasaki.pdf),
わざと meant something closer to わざわざ in the sense of "to bother to do ～". This
sense of わざと is obsolete now. However the word わざわざ(し) also existed in archaic
Japanese and it meant "contrived; artificial". I could not find the direct
source that describes when and how わざわざ was coined, but they are probably not
in a simple "original-derived" relationship as you might expect. Both existed,
but there was a large shift in meaning.
