subgrammar
nounEtymology From sub- + grammar.

A grammar that makes up part of a larger grammar; a subdivision of a grammar.
- The 'original' subgrammars can be seen as a concatenation' or composition of some of these parts with the requirement that the export category of a preceding subgrammar in the concatenation must be the head category of a subsequent subgrammar.2013, M.T.
