'''NB.''' The notation in this next section needs fixing.
The definitions of these syntactic operations can now be organized in a slightly better fashion, for both conceptual and computational purposes, by making a few additional conventions and auxiliary definitions.

Having defined the basic operations of concatenation and surcatenation
Having defined the basic operations of concatenation and surcatenation on arbitrary strings, in effect, giving them operational meaning for the all-inclusive language <math>\mathfrak{L} = \mathfrak{A}^*,</math> it is time to adjoin the notion of a more discriminating grammaticality, in other words, a more properly restrictive concept of a sentence.
