That is not always the case, however; the isolation form itself is sometimes subject to neutralization that does not apply to some other instances of the morpheme. For example, the French word "petit" ("small") is pronounced in isolation without the final sound, but in certain derived forms (such as the feminine "petite"), the [t is heard. If the isolation form were adopted as the underlying form, the information that there is a final "t" would be lost, and it would then be difficult to explain the appearance of the "t" in the inflected forms. Similar considerations apply to languages with final obstruent devoicing, in which the isolation form undergoes loss of voicing contrast, but other forms may not.
