Editing Lenition (section)

==Fortition==
{{main|Fortition}}
Fortition is the opposite of lenition: a consonant mutation in which a consonant changes from one considered weak to one considered strong. Fortition is less frequent than lenition in the languages of the world, but word-initial and word-final fortition is fairly frequent.

Italian, for example, presents numerous regular examples of word-initial fortition both historically (Lat. {{lang|la|Januarius}} with initial {{IPA|/j/}} > {{lang|it|gennaio}}, with {{IPA|[dʒ]}}) and synchronically (e.g., {{IPA|/ˈkaza/}} "house, home" → {{IPA|[ˈkaːza]}} but {{IPA|/a ˈkaza/}} "at home" → {{IPA|[aˈkːaːza]}}).

Catalan is among numerous Romance languages with diachronic [[Final-obstruent devoicing|word-final devoicing]] ({{lang|la|frigidus}} > {{IPA|*/ˈfɾɛd/}} > {{lang|ca|fred}} {{IPA|[ˈfɾɛt]}}. Fortition also occurs in Catalan for {{IPA|/b d ɡ/}} in consonant clusters with a lateral consonant (Lat. {{lang|la|populus}} > {{lang|ca|poble}} {{IPA|[ˈpɔbːɫə]}} or {{IPA|[ˈpɔpːɫə]}}.

Word-medially, {{IPA|/lː/}} is subject to fortition in numerous Romance languages, ranging from {{IPA|[ɖː]}} or {{IPA|[dː]}} in many [[languages of Italy|speech types on Italian soil]] to {{IPA|[dʒ]}} in some varieties of Spanish.
