+--1 A Simple English Resource Morphology
+--
+-- Aarne Ranta 2002 -- 2005
+--
+-- This resource morphology contains definitions needed in the resource
+-- syntax. To build a lexicon, it is better to use $ParadigmsEng$, which
+-- gives a higher-level access to this module.

+--2 Phonology

+-- To regulate the use of endings for both nouns, adjectives, and verbs:

+    _   => init fly + "ie" + s
+    } ;
+
+
+--2 Nouns
+--
+-- For conciseness and abstraction, we define a worst-case macro for
+-- noun inflection. It is used for defining special case that
+-- only need one string as argument.
