Use this tag to indicate the list of inflections attached to a grammatical group
7.1 Inflections for Dictionaries
When building dictionaries, you may have multiple inflected forms of a single root word that should
access the same entry. However, adding all of these inflected forms under the orthography
(pronunciation) of a single entry leads to the generation of a large index, which negatively affects
performance and user experience. Kindle has a disinflection engine that uses a set of rules for
disinflecting any given word to its headword. The index then has only the headword to look up.
To generate the set of disinflection rules for the dictionary, the input must include some information about
the inflections. There are two ways to provide this information: simplified inflection syntax and advanced
inflection syntax.
7.1.1 Simplified inflection syntax
Simplified inflection syntax is a very simple way of giving information about the inflections. Previous
versions of the file format supported using the infl attribute in either the or the
tag and specifying a comma-separated list of inflected forms. This syntax is now
deprecated, as it is not as accurate when disinflecting.
7.1.2 Advanced inflection syntax
Inflections are handled by the inflection index built into the dictionary by the creator software, based on
the inflected forms tagged in the content using the tag. Inflections are attached to the
orthography of the entry. Inflections must be specified inside an tag. If an entry has multiple
orthographies, each must have its own inflections.
Example:
record
The inflgrp and name attributes are optional. The idx:infl, idx:iform, and value attributes are
required.
7.2 Custom OPF Metadata for Dictionaries
Set a source language and a target language for dictionaries. If a dictionary has multiple indexes, specify
the name of the primary lookup index.
Example:
en-us
en-us
Index Name goes here
