reciprocal
A morphological and syntactic term: In syntax, a reciprocal construction refers to a type of relationship that is shared between noun phrases. In reciprocal constructions, each N occupies both the thematic role of agent and patient with respect to the other. For example: ‘John and Mary understand each other’. In morphology, reciprocal affixes, particles, words and phrases are the elements that create reciprocal action. In English, the phrase ‘each other’ is used for this purpose.

recursion
The ability to embed certain types of phrases indefinitely to embellish a sentence. This is the creative aspect of forming sentences. ex. The German Shepard [digging a hole [in the garden] [under the tree]], loves to play [in the snow] [with his ball]]. All phrases which are bracketed are embedded inside the NP and VP and are added as embellishment. We could continue to add such phrases to make the sentence as long and as creative as desired.
