+--2 Clauses
+
+-- The $NP VP$ predication rule form a clause whose linearization
+-- gives a table of all tense variants, positive and negative.
+-- Clauses are converted to $S$ (with fixed tense) with the
+-- $UseCl$ function below.

+
+-- Using an embedded sentence as a subject is treated separately.
+-- This can be overgenerating. E.g. "whether you go" as subject
+-- is only meaningful for some verb phrases.
+
+    PredSCVP  : SC -> VP -> Cl ;         -- that she goes is good
+
+--2 Clauses missing object noun phrases
+
+-- This category is a variant of the 'slash category' $S/NP$ of
+-- GPSG and categorial grammars, which in turn replaces
+-- movement transformations in the formation of questions
+-- and relative clauses. Except $SlashV2$, the construction 
+-- rules can be seen as special cases of function composition, in
+-- the style of CCG.
+-- *Note* the set is not complete and lacks e.g. verbs with more than 2 places.

+    SlashVS   : NP -> VS -> SSlash -> ClSlash ; -- (whom) she says that he loves
+
+--2 Imperatives
+
+-- An imperative is straightforwardly formed from a verb phrase.
+-- It has variation over positive and negative, singular and plural.
+-- To fix these parameters, see [Phrase Phrase.html].
+
+    ImpVP     : VP -> Imp ;              -- love yourselves
+
+--2 Embedded sentences
+
+-- Sentences, questions, and infinitival phrases can be used as
+-- subjects and (adverbial) complements.

+
+--2 Sentences
+
+-- These are the 2 x 4 x 4 = 16 forms generated by different
+-- combinations of tense, polarity, and
+-- anteriority, which are defined in [``Common`` Common.html].

+
+-- An adverb can be added to the beginning of a sentence, either with comma ("externally")
+-- or without:
+
+    AdvS     : Adv -> S  -> S ;            -- then I will go home
+    ExtAdvS  : Adv -> S  -> S ;            -- next week, I will go home
+
+-- This covers subjunctive clauses, but they can also be added to the end.
+
+    SSubjS   : S -> Subj -> S -> S ;       -- I go home if she comes
+
+-- A sentence can be modified by a relative clause referring to its contents.
+
+    RelS     : S -> RS -> S ;              -- she sleeps, which is good
+
+---- A sentence can also be post-modified by a subjunct sentence.
+
+----    ModSubjS : S -> Subj -> S -> S ;       -- she sleeps, because she is old 
+---- cf. Adverb.SubjS
+

+-- Examples for English $S$/$Cl$:
+
+  Pres  Simul  Pos  ODir  : he sleeps
+  Pres  Simul  Neg  ODir  : he doesn't sleep
+  Pres  Anter  Pos  ODir  : he has slept
+  Pres  Anter  Neg  ODir  : he hasn't slept
+  Past  Simul  Pos  ODir  : he slept
+  Past  Simul  Neg  ODir  : he didn't sleep
+  Past  Anter  Pos  ODir  : he had slept
