This module implements the underlying processing of {{form of}},
{{inflection of}} and specific variants such as {{past participle of}}
and {{alternative spelling of}}. Most of the logic in this file is to
handle tags in {{inflection of}}. Other related files:
* [[Module:form of/templates]] contains the majority of the logic that
implements the templates themselves.
* [[Module:form of/data]] is a data-only file containing information on
the more common inflection tags, listing the tags, their shortcuts,
the category they belong to (tense-aspect, case, gender, voice-valence,
etc.), the appropriate glossary link and the wikidata ID.
* [[Module:form of/data2]] is a data-only file containing information on
the less common inflection tags, in the same format as
[[Module:form of/data]].
* [[Module:form of/cats]] is a data-only file listing the
language-specific categories that are added when the appropriate
combinations of tags are seen for a given language.
* [[Module:form of/pos]] is a data-only file listing the recognized
parts of speech and their abbreviations, used for categorization.
FIXME: This should be unified with the parts of speech listed in
[[Module:links]].
* [[Module:form of/functions]] contains functions for use with
[[Module:form of/data]] and [[Module:form of/cats]]. They are
contained in this module because data-only modules can't contain
code. The functions in this file are of two types:
(1) Display handlers allow for customization of the display of
multipart tags (see below). Currently there is only one
such handler, for handling multipart person tags such as
'1//2//3'.
(2) Cat functions allow for more complex categorization logic,
and are referred to by name in [[Module:form of/cats]].
Currently no such functions exist.
The following terminology is used in conjunction with {{inflection of}}:
* A TAG is a single grammatical item, as specified in a single numbered
parameter of {{inflection of}}. Examples are 'masculine', 'nominative',
or 'first-person'. Tags may be abbreviated, e.g. 'm' for 'masculine',
'nom' for 'nominative', or '1' for 'first-person'. Such abbreviations
are called SHORTCUTS, and some tags have multiple equivalent shortcuts
(e.g. 'p' or 'pl' for 'plural'). The full, non-abbreviated form of
a tag is called its CANONICAL FORM.
* The DISPLAY FORM of a tag is the way it's displayed to the user. Usually
the displayed text of the tag is the same as its canonical form, and it
normally functions as a link to a glossary entry explaining the tag.
Usually the link is to an entry in [[Appendix:Glossary]], but sometimes
the tag is linked to an individual dictionary entry or to a Wikipedia
entry. Occasionally, the display text differs from the canonical form of
the tag. An example is the tag 'comparative case', which has the display
text read as simply 'comparative'. Normally, tags referring to cases don't
have the word "case" in them, but in this case the tag 'comparative' was
already used as a shortcut for the tag 'comparative degree', so the tag was
named 'comparative case' to avoid clashing. A similar situation occurs
with 'adverbial case' vs. the grammar tag 'adverbial' (as in 'adverbial
participle').
* A TAG SET is an ordered list of tags, which together express a single
inflection, for example, '1|s|pres|ind', which can be expanded to
canonical-form tags as 'first-person|singular|present|indicative'.
Multiple tag sets can be specified in a single call to {{inflection of}}
by separating the individual tag sets with a semicolon, e.g.
'1|s|pres|ind|;|2|s|imp', which specifies two tag sets, '1|s|pres|ind'
as above and '2|s|imp' (in canonical form,
'second-person|singular|imperative').
* A MULTIPART TAG is a tag that embeds multiple tags within it, such as
'f//n' or 'nom//acc//voc'. These are used in the case of [[syncretism]],
when the same form applies to multiple inflections. Examples are the
Spanish present subjunctive, where the first-person and third-person
singular have the same form (e.g. [[siga]] from [[seguir]] "to follow"),
or Latin third-declension adjectives, where the dative and ablative
plural of all genders have the same form (e.g. [[omnibus]] from [[omnis]]
"all"). These would be expressed respectively as '1//3|s|pres|sub'
and 'dat//abl|m//f//n|p', where the use of the multipart tag compactly
encodes the syncretism and avoids the need to individually list out
all of the inflections. Multipart tags currently display as a list
separated by "and", ''dative and ablative'' or
''masculine, feminine and neuter'' where each individual word is linked
appropriately. As a special case, multipart tags involving persons display
specially; for example, the multipart tag ''1//2//3'' displays as
''first-, second- and third-person'', with the word "person" occurring
only once.
* A TWO-LEVEL MULTIPART TAG is a special type of multipart tag that
joins two or more tag sets instead of joining individual tags. The tags
within the tag set are joined by a colon, e.g. '1:s//3:p', which is
displayed as ''first-person singular and third-person plural'', e.g.
for use with the form [[μέλλον]] of the verb [[μέλλω]] "to intend",
which uses the tag set '1:s//3:p|impf|actv|indc|unaugmented' to express
the syncretism between the first singular and third plural forms of the
imperfect active indicative unaugmented conjugation. Two-level multipart
tags should be used sparingly; if in doubt, list out the inflections
separately.
* A MULTIPART TAG SHORTCUT is a shortcut that expands into a multipart
tag, for example '123', which expands to the multipart tag '1//2//3'.
Only the most common such combinations exist as shortcuts.
* A LIST TAG SHORTCUT is a special type of shortcut that expands to a list
of tags instead of a single tag. For example, the shortcut '1s' expands to
'1|s' (first-person singular). Only the most common such combinations
exist as shortcuts.
