Assimilation, or the influence of one sound on an adjacent sound,
is perhaps the most pervasive process. Assimilation processes changed
Latin /k/ when followed by /i/ or /y/, first to /ky/, then to "ch", then
to /s/, so that Latin faciat /fakiat/ 'would make' became
fasse /fas/ in Modern French (the subjunctive of the
verb faire'to make').Palatalization is a kind of assimilation.
