 '''Subcategorization frames''' are sets of rules used to generate syntactic structures out of the [[base form]].
 == What are subcategorization frames ? ==
 Subcategorization frames are sets of [[subcategorization]] rules that apply for a wide range of cases, i.e., that are regular.
 == When to use subcategorization frames ==
 Subcategorization frames are used in case of [[valency|valent]] words whose syntactic needs follow a general rule, i.e., whenever there can be stated a regular pattern for generating constituents linked to the base form, such as specifiers, complements and adjuncts.

 == When not to use subcategorization frames ==
 Subcategorization frames are not used in case of avalent words or in case of irregular behaviour, which is described by [[subcategorization rules]].
 For instance, very few verbs, in English, admit more than two arguments, such as "to bet" in "I bet you ten pounds that they lose". This syntactic behavior, which can be described by the rule VS(NP)VC(PPR)VC(NP)VC(CH([that]));, as very specific, is likely to be defined as a subcategorization rule, to be created inside the dictionary, rather than as a subcategorization frame, created in the grammar.

	~~== Syntax ==~~

	~~Subcategorization frames are expressed by [[S-rule]]s, a special formalism for representing the syntactic structure of phrases.~~

	~~<HD SYNTACTIC ROLE>(<ARGUMENT>);~~

	~~Where:<br/>~~
	~~<HD SYNTACTIC ROLE> is a head-driven [[Syntactic role]] (VA, VC, VS, VH, etc) of the term required by the base form; and<br />~~
	~~<ARGUMENT> is the term required by the base form to saturate its syntactic structure, i.e., in order to form the simplest maximal projection (NP, VP, JP, AP, PP, DP). <br />~~

	~~== Observations ==~~
	~~#There must be as many syntactic roles as [[Subcategorization#Necessary_and_optional_arguments\|necessary arguments]] inside a subcategorization frame~~
	~~#*VS(NP); (intransitive verbs)~~
	~~#*VS(NP)VC(NP); (direct transitive verbs)~~
	~~#*VS(NP)VC(NP)VC(NP); (a verb with two direct objects)~~
	~~#*VS(NP)VC(NP)VC(NP)VC(NP); (a verb with three direct objects)~~
	~~#The arguments must be represented by their corresponding maximal projection (NP,VP,etc.) or by a XH relation in case the argument is necessarily headed by a given word:~~
	~~#*VS(NP)VC(NP); (verbs taking a NP as specifier and another NP as complement)~~
	~~#*VS(NP)VC(PH([of])); (verbs taking a NP as specifier a PP introduced by [of] as a complement = PH([of]);)~~
	~~#The arguments may have as many features as necessary, provided that they are '''necessary''' and represented according to the [[Tagset]].~~
	~~#*VS(NP,NOM); (verbs taking a NP in the nominative case (NOM) as specifier)~~
	~~#*VS(NP,NOM)VC(NP,ACC); (verbs taking a NP in the nominative case as specifier and another NP in accusative case as complement)~~
	~~#*VS(NP,PPR,NOM); (verbs taking a NP that is a personal pronoun (PPR) in the nominative case (NOM))~~
	~~#:Features of arguments may be omitted if they are default~~
	~~#:If the NP is always NOM in VS there is no need for VS(NP,NOM); the frame must be simply VS(NP);~~
	~~#Maximal projections must explicitly indicate the value of the phrase when they are fixed.~~
	~~#*NS(DP([the])); (the noun requires the DP "the", i.e., the whole DP is fixed and cannot be modified)~~
	~~#:compare with~~
	~~#*NS(DH([the])); (the noun requires a DP headed by "the", i.e., the DP structure is variable, provided that it is headed by "the")~~
	~~#Strings must be represented between "quotes" while headwords must be represented between [brackets].~~
	~~#*VC(PH([of])); (the word "of" is supposed to be included in the dictionary and, therefore, must be represented as an [entry]~~
	~~#*VC("to the lions"); (the expression "to the lions" is not supposed to be included in the dictionary and, therefore, must be represented as a "string"~~
