-pro- attached to a substance, type of cell, or chemical name can also refer to a developmental precursor to that substanceassimilation-predictable
-effects on pronunciation can change spelling
-ex. inpuls --> impulse
-since in in-puls is difficult to say but im-puls is almost the same and much easier, the "n" of the prefix is assimilated to the initial sound of the root
-more likely to happen if the prefix and beginning of root are pronounced in very different areas of the mouthprefixes ending in -n (con-, in-)N + r = rr correlation
