:Lexical conditioning:

The situation where a phonetic or phonological feature is present in only some items and not in others which appear to be similar in structure. An example from the accentuation of compounds involves structures of the form Ni + Nc, where Ni is a noun referring to an ingredient and Nc is a noun referring to a confection. The general pattern for such compounds is that the main accent falls within Nc: ˌapple ‘pie, ˌchocolate ‘sauce, ˌraspberry ‘jelly. However, there is a small group of words, including bread, cake, and water which do not get the main accent: ˈraisin ˌbread, ˈchocolate ˌcake, ˈsoda ˌwater.
