The coordination test consists in coordinating two units A and B in the context of C in order to analyze either the degree of autonomy of A and B or the scope of C.
f are from Zwicky 1977:5.
| . | a. | Je connais Jean et je crains Jean. |
| b. | Je connais et je crains Jean. | |
| French | I know and fear John. |
| . | a. | Je le connais et je le crains. |
| b. | *Je le connais et crains. | |
| French | I know and fear him. |
Generally, parts of words cannot be deleted under coordination (Zwicky 1977:3):
yellowish or greyish ≠ yellow or greyish
dancing and singing ≠ dance and singing
In other cases, however, this is possible:
German diagnostizier- und therapierbar ‘capable of diagnosis and therapy’
Staats- und Völkerrecht ‘public and international law’
