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:

Language-specific tags override general tags. appropriate combinations of tags are seen for a given language. categorization. FIXME: This should be unified with the parts of speech listed in Module:links. They are contained in this module because data-only modules can't contain code. The functions in this file are of two types: one such handler, for handling multipart person tags such as `1//2//3`. Currently no such functions exist.

The following terminology is used in conjunction with inflection of:

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 aliases, and some tags have multiple equivalent aliases (e.g. `p` or `pl` for `plural`). The full, non-abbreviated form of a tag is called its canonical form. 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 an alias 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`). which can be expanded to canonical-form tags as `first-person|singular|present|indicative`. `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`). Multiple tag sets specified in a single call to inflection of are specified in this fashion. Conjoined tag sets can also occur in list-tag shortcuts. 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. from  ), or Latin third-declension adjectives, where the dative and ablative plural of all genders have the same form (e.g. from ). 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 a slash, e.g. dative/ablative or masculine/feminine/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. 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  of the verb , 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. [FIXME: Make two-level multipart tags obsolete.] Aliases are a particular type of shortcut whose expansion is a single non-multipart tag. multipart tag `1//2//3`. Only the most common such combinations exist as shortcuts. the shortcut `1s` expands to `1|s` (first-person singular). Only the most common such combinations exist as shortcuts. sets). For example, the English language-specific shortcut `ed-form` expands to `spast|;|past|part`, expressing the common syncretism between simple past and past participle in English (and in this case, `spast` is itself a list shortcut that expands to `simple|past`). ]==]
