Subcategorization rules
Subcategorization rules are sets of rules used to generate particular syntactic structures out of the base form.

What are subcategorization rules
Subcategorization rules are rules for describing the necessary constituents for a form to project its corresponding maximal projection.
When not to use subcategorization rules
Subcategorization rules are used in case of valent words that have an irregular syntactic behaviour.
When not to use subcategorization frames
Subcategorization rules are not used in case of avalent words or in case of valent words that have a regular syntactic behaviour (which is described by subcategorization frames).
Syntax
Subcategorization rules are expressed by S-rules, a special formalism for representing the syntactic structure of phrases.
<SYNTACTIC ROLE>(<REQUIRED>);
Where:
<SYNTACTIC ROLE> is the Syntactic roles (VA, VC, VS, VH, etc) of the term required by the base form; and
<REQUIRED> is the term required by the base form to saturate its syntactic structure. It is a maximal projection (NP, VP, JP, AP, PP, DP), a head or a combination of both.
