[2] It was in this work that she proposed "feature percolation," a mechanism by which the properties of lexical items are inherited by their larger constituent structures, and which she articulates more fully in Lieber 1992 (77ff).
Syntacticians and morphologists have made use of the concept of feature percolation in many different ways since Lieber's first proposal.
Lieber is the author of Deconstructing Morphology: Word Formation in Syntactic Theory (Chicago: Chicago University Press, 1992), an influential[citation needed] attempt to reduce morphology to the syntactic principles of government and binding theory.
In Deconstructing Morphology, Lieber makes two statements that are often quoted: "no one has yet succeeded in deriving the properties of words and the properties of sentences from the same principles of grammar," and "the conceptually simplest possible theory would then be the one in which all morphology is done as a part of syntax" (Lieber 1992: 21).
In 2015 she and co-authors Laurie Bauer and Ingo Plag were the recipients of the Linguistic Society of America's Leonard Bloomfield Book Award for their 2013 work, The Oxford Reference Guide to English Morphology.
