Editing Lenition (section)

===Sonorization===
The sonorization type involves voicing. Sonorizing lenition involves several sound changes: voicing, approximation, and vocalization.{{clarify|reason=More sound changes are involved, and if there are specific names for the different changes, these should be listed.|date=February 2015}}
* {{IPA|[t]}} > {{IPA|[d]}} (voicing, example in [[Korean language|Korean]])
* {{IPA|[d]}} > {{IPA|[ð]}} (approximation, example in [[Spanish language|Spanish]])
* {{IPA|[d]}} > {{IPA|[i]}} (vocalization)

Sonorizing lenition occurs especially often intervocalically (between vowels).  In this position, lenition can be seen as a type of [[assimilation (linguistics)|assimilation]] of the consonant to the surrounding vowels, in which features of the consonant that are not present in the surrounding vowels (e.g. obstruction, voicelessness) are gradually eliminated.

Some of the sounds generated by lenition are often subsequently "normalized" into related but cross-linguistically more common sounds.  An example would be the changes {{IPA|[b]}} → {{IPA|[β]}} → {{IPA|[v]}} and {{IPA|[d]}} → {{IPA|[ð]}} → {{IPA|[z]}}.  Such normalizations correspond to diagonal movements down and to the right in the above table.  In other cases, sounds are lenited and normalized at the same time; examples would be direct changes {{IPA|[b]}} → {{IPA|[v]}} or {{IPA|[d]}} → {{IPA|[z]}}.

====Vocalization====
[[L-vocalization|''L''-vocalization]] is a subtype of the sonorization type of lenition. It has two possible results: a velar approximant or back vowel, or a palatal approximant or front vowel. In [[French language|French]], ''l''-vocalization of the sequence {{IPA|/al/}} resulted in the [[diphthong]] {{IPA|/au/}}, which was [[monophthongized]], yielding the [[monophthong]] {{IPA|/o/}} in Modern French.
