-ise/-ize

In PHONETICS, a SUFFIX used to identify the place or process of ARTICULATION of a secondary STRICTURE, as in ‘labialize’, ‘velarized’; an associated process suffix is -isation/-ization. For example, [t^j] would be described as a ‘palatalized t’. Both dynamic and static interpretations are used: a sound is described as ‘labialized’ both (a) during the process of labialization, and (b) once that process is over.

In HISTORICAL LINGUISTICS and SOCIOLINGUISTICS, a SUFFIX used to characterize a change of a sound from one place of ARTICULATION to another: for example, a change from [k] to [c] or [t] to [c] could be described as a process of ‘palatalization’. This sense needs to be kept clearly distinct from (1) above: the palatalization of [t] as [t^j] is very different from [t] as [c].
