text: # Diachronics of plural inflection in the Gallo-Italian languages
  
  The general lines of diachronics of Lombard and Piedmontese plural declension are drawn here:
  
  ## Feminine
  
  In Lombard and Piedmontese, feminine plural is generally derived from Latin first declension accusative -as (compare Romance plurals § Origin of vocalic plurals); nouns from other classes first collapsed there; some concrete realisations are:
  
  * -as > -a
  * -as > -es > -e
  * -as > -es > -ei > -i
  * -as > -es > -ei > -i > -e
  * -as > -es > -ei > -i > -∅
  
  ## Masculine
  
  On the contrary, masculine plural is generally derived from Latin second declension nominative -i; this suffix eventually drops or gives rise to palatalisation or metaphonesis; some concrete realisations are:
  
  * -li > -lj > -gl > -j
  * -ni > -nj > -gn
  * -ti > -tj > -cc
  * Metaphonesis (in regression) : orti > öört;
  * Neutralisation: -i > -∅
