Final answer:
Morris uses the word "object" to refer to the physical sculptures he creates and as a theoretical focus in his art practice, particularly shown in the example of the L-Beams.
Step-by-step explanation:
From the given excerpts of Morris's work, the word Morris uses to refer to things could be "object" as seen in the context of his discussions about sculpture. The term "object" captures both the physical sculptures he creates and the subject of his theoretical examination into art practice. Morris emphasizes the dual nature of objects as physical entities and as participants in a broader discourse within the art community. This concept is especially evident in the discussions of the L-Beams, where he contrasts the experienced variable (perception) with the known constant (reality).
