In many cases, it is more appropriate to assume that the base has a tone or stress pattern which is replaced by another in inflection or derivation. An example in English is initial-stressed nouns that are derived from verbs with final stress (e.g. prodúce/prəˈdjuːs/ > próduce/ˈprɒdjuːs/). Another is the Mandarin好hǎo ("to be good") and 好hào ("to find good"), where the tone changes from low to falling. Some linguists use suprafix for such a suprasegmental change (in fact, Nida himself considered a distinction between additive suprafixes and replacive suprafixes).
