Missing laws from Collinge[edit]

A sorted working list with comments. At least the following would probably need to be added:

Fortunatov's law I
*l + dental > retroflex in Indo-Aryan
Law of Palatals
*K⁽ʷ⁾e > *Ča in Indo-Iranian
Rix's law
*HR̥C- is subject to laryngeal vowel coloring in Greek
Sievers' law II
*gʷʰ > *w in Germanic, various conditions have been proposed
Thurneysen's law
proposes fricative voicing dissimilation in Gothic after unstressed syllables; many details disputed
Thurneysen-Havet's law
*o > *a in Latin, at minimum before *wV́
Wackernagel's law II
*V₁V₂ > *V̄₂ crasis in Greek compound words

Missing laws concerning accentuation are particularly numerous:

From Balto-Slavic or Slavic: Dolobko's law, Ebeling's law, Fortunatov's law II, Garde's rule, Hartmann's law, Illič-Svityč's law, Kortlandt's law, Nieminen's law, Pedersen's law II, Šaxmatov's law
From Greek: Bártoli's law, Hirt's law II, Vendryes' law, Wheeler's law

Proposed but obsolete or disputed laws from Appendix I:

Bugge's rule: proposes as an extension to Verner's that voiceless stops > voiced fricatives word-initially when at least two syllables away from stress
Endzelin's law: proposes *éi > *ḗ > ie in Baltic
Georgiev's law: proposes word-initial *V̆CC > *CV̄C in Slavic
Streitberg's law: proposes that long grades would always occur preceding a zero grade

Some laws seem too narrow or too general in scope to belong in this article:

while some are morphological or syntactic rather than sound laws:

Caland's law = Caland system; not usually considered a "law" (as also admitted by Collinge)
Wackernagel's law: governs the sentence position of clitics
Watkin's law: a general law of the special role of 3rd person in personal paradigm evolution
