schematic

Etymology

From scheme or schema.

adj

1. Represented too simply or in an overly formulaic way, reflecting a shallow or incomplete understanding of complex subject matter.
2. Sketchy, incomplete.
3. Relating to a schema.
   Given the terminology we have introduced here, we can say that all of the bracketed phrases in (3) above are of the schematic form (4) below: (4) Specifier + Head + Complement Now, we have already argued in the case of Noun Phrases that a Head Noun together with its Complement form an N-bar; and that this N-bar together with its Specifier ( = Determiner) forms an N-double-bar. 1988, Andrew Radford, Transformational grammar: a first course, Cambridge, UK: Cambridge University Press, page 228

noun

1. A simplified line drawing used by scientists, engineers, technologists and others to illustrate a system at an abstract level. Schematic drawings often use standard symbols for clarity.
