ויכוח

Action noun of the verb ויכח‎ (vikákh), from the root ו־כ־ח‎ (v-k-kh).

ויכוח \ וִכּוּחַ • (vikúakh) m (plural indefinite ויכוחים \ וִכּוּחִים‎, singular construct ויכוח \ וִכּוּחַ־, plural construct ויכוחי \ וִכּוּחֵי־‎)

1. An argument, a verbal dispute, a quarrel: an exchange of words between parties who disagree about something.

   אין ויכוח כי […] — éin vikúakh kí […] — There is no dispute that […] or No one disputes that […]

2. (וִכּוּחַ־‎, vikúakh-) Singular construct form of ויכוח \ וִכּוּחַ‎‎.

• In current usage, the noun ויכוח (vikúakh) is much more common than the verb ויכח‎ (vikákh) from which it derives. The more common verb is התווכח‎ (hitvakéakh); indeed, etymological considerations aside, ויכוח (vikúakh) may perhaps be thought of as an action noun for the latter. (A regularly formed action noun התווכחות‎ (hitvak'khút) does exist, but is much less common.)
