cop
: copula
The dependency type cop
is reserved for a copular auxiliary だ / da.
The auxiliary typically follows a noun phrase to form a copular clause.
A postpositional phrase with a nominative case is commonly needed to complete sentence.
For example, dependencies for 太郎 は 学生 だ 。/ Taro ha gakusei da “Taro is a student.” are as follows.
Note that we treat the auxiliary だ / da after adjectives as aux. Therefore dependencies for さくら が きれい だ 。 / sakura ga kirei da “The cherry blossoms are beautiful.” do not include the `cop’ relation.
