The -ず
form of a verb means "without doing" and is roughly equivalent to ないで
. It's not a contraction of anything and is a verb form on its own.
The -ず
form is formed by taking the -ない
form of a verb and replacing the -ない
with -ず
. For the irregular verbs, する
becomes せず
and [来]{く}る
becomes [来]{こ}ず
.
what is the original form
The verb する.
and how does it become せず?
ず is an auxiliary verb ([助動詞]{じょどうし}) which attaches to the [未然形]{みぜんけい} of the verb. せ is one 未然形 of する and is the one which ず attaches to.
