Usage notes

edit

A morphologically derived deverbal noun, such as this entry, is a countable noun. The corresponding uncountable verbal noun is attained in Welsh by employing the verbnoun or dictionary form of the related verb as a masculine singular noun.

Dyddodiad is not used for the chemical sense of precipitation, for which see gwaddodiad.
