TERMINOLOGY:

-- "slot" = A particular combination of tense/mood/person/number/etc. Example slot names for verbs are "pres_1s" (present indicative first-person singular), "pres_sub_2s" (present	 subjunctive second-person singular) "impf_sub_3p" (imperfect subjunctive third-person plural). Each slot is filled with zero or more forms.

-- "form" = The conjugated Galician form representing the value of a given slot.

-- "lemma" = The dictionary form of a given Galician term. For Galician, always the infinitive. ]=]

Vowel alternations:

: 'i' in pres1s, imp2s and the whole present subjunctive; 'e' elsewhere when stressed. Generally 'e' otherwise when unstressed. E.g. sentir, conseguir (the latter additionally with 'gu-g' alternation). : 'u' in pres1s, imp2s and the whole present subjunctive; 'o' elsewhere when stressed. Generally 'u' otherwise when unstressed. E.g. durmir, subir. : 'i' whenever stressed (in the present singular and third plural) and throughout the whole present subjunctive. Otherwise 'e'. E.g. vestir, pedir. : 'u' whenever stressed (in the present singular and third plural) and throughout the whole present subjunctive. Otherwise 'o'.

-- Special slots used to handle non-reflexive parts of reflexive verbs in. For example, for a	-- reflexive-only verb like arrepentirse, we want to be able to use on arrepinta (which	-- should mention that it is a part of 'me arrepinta', first-person singular present subjunctive, and	-- 'se arrepinta', third-person singular present subjunctive) or on arrepentimos (which should mention that it	-- is a part of 'arrepentímonos', first-person plural present indicative or preterite). Similarly, we want to use -- on arrepentindo (which should mention that it is a part of 'se ... arrepentindo',	-- syntactic variant of arrepentíndose, which is the gerund of arrepentirse). To do this, we need to be -- able to map non-reflexive parts like arrepinta, arrepentimos, arrepentindo, etc. to their reflexive -- equivalent(s), to the tag(s) of the equivalent(s), and, in the case of forms like arrepentindo, -- arrepentir and imperatives, to the separated syntactic variant of the verb+clitic combination. We do this by	-- creating slots for the non-reflexive part equivalent of each basic reflexive slot, and for the separated -- syntactic-variant equivalent of each basic reflexive slot that is formed of verb+clitic. We use slots in this -- way to deal with multiword lemmas. Note that we run into difficulties mapping between reflexive verbs, -- non-reflexive part equivalents, and separated syntactic variants if a slot contains more than one form. To	-- handle this, if there are the same number of forms in two slots we're trying to match up, we assume the forms -- match one-to-one; otherwise we don't match up the two slots (which means won't work in this	-- case, but such a case is extremely rare and not worth worrying about).

Built-in (usually irregular) conjugations.

Each entry is processed in turn and consists of an object with two fields: 1. match=: Specifies the built-in verbs that match this object. 2. forms=: Specifies the built-in stems and forms for these verbs.

The value of match= is either a string beginning with "^" (match only the specified verb), a string not beginning with "^" (match any verb ending in that string), or a function that is passed in the verb and should return the prefix of the verb if it matches, otherwise nil. The function match_against_verbs is provided to facilitate matching a set of verbs with a common ending and specific prefixes (e.g. ter and ater but not abater, etc.).

The value of forms= is a table specifying stems and individual override forms. Each key of the table names either a stem (e.g. `pres_stressed`), a stem property (e.g. `vowel_alt`) or an individual override form (e.g. `pres_1s`). Each value of a stem can either be a string (a single stem), a list of strings, or a list of objects of the form {form = STEM, footnotes = {FOONOTES}}. Each value of an individual override should be of exactly the same form except that the strings specify full forms rather than stems. The values of a stem property depend on the specific property but are generally strings or booleans.

In order to understand how the stem specifications work, it's important to understand the phonetic modifications done by combine_stem_ending. In general, the complexities of predictable prefix, stem and ending modifications are all handled in this function. In particular:

1. Spelling-based modifications (c/z, g/gu, gu/gü, g/j) occur automatically as appropriate for the ending. 2. If the stem begins with an acute accent, the accent is moved onto the last vowel of the prefix (for handling verbs  in -uar such as minguar, pres_3s 'míngua'). 3. If the ending begins with a double asterisk, this is a signal to conditionally delete the accent on the last letter of the stem. "Conditionally" means we don't do it if the last two letters would form a diphthong without the accent on the second one (e.g. in sair, with stem 'saí'); but as an exception, we do delete the accent in stems ending in -guí, -quí (e.g. in conseguir) because in this case the ui isn't a diphthong. 4. If the ending begins with an asterisk, this is a signal to delete the accent on the last letter of the stem, e.g.  fizé -> fizermos. Unlike for **, this removal is unconditional, so we get e.g. 'sairmos' not #'saírmos'. 5. If ending begins with i, it must get an accent after an unstressed vowel (in some but not all cases) to prevent the two merging into a diphthong. See combine_stem_ending for specifics.

The following stems are recognized:

-- pres_unstressed: The present indicative unstressed stem (1p, 2p). Also controls the imperative 2p and gerund. Defaults to the infinitive stem (minus the ending -ar/-er/-ir/-or). -- pres_stressed: The present indicative stressed stem (1s, 2s, 3s, 3p). Also controls the imperative 2s. Default is empty if indicator `no_pres_stressed`, else a vowel alternation if such an indicator is given (e.g. `ue`, `ì`), else the infinitive stem. -- pres1_and_sub: Overriding stem for 1s present indicative and the entire subjunctive. Only set by irregular verbs and by the indicators `no_pres_stressed` (e.g. precaver) and `no_pres1_and_sub` (since verbs of this sort,	 e.g. puir, are missing the entire subjunctive as well as the 1s present indicative). Used by many irregular verbs, e.g. caber, verbs in '-air', dizer, ter, valer, etc. Some verbs set this and then supply an override for the pres_1s if it's irregular, e.g. saber, with irregular subjunctive stem "saib-" and special 1s present indicative "sei". -- pres1: Special stem for 1s present indicative. Normally, do not set this explicitly. If you need to specify an    irregular 1s present indicative, use the form override pres_1s= to specify the entire form. Defaults to pres1_and_sub if given, else pres_stressed. -- pres_sub_unstressed: The present subjunctive unstressed stem (1p, 2p). Defaults to pres1_and_sub if given, else the infinitive stem. -- pres_sub_stressed: The present subjunctive stressed stem (1s, 2s, 3s, 1p). Defaults to pres1. -- sub_conj: Determines the set of endings used in the subjunctive. Should be one of "ar" or "er". -- impf: The imperfect stem (not including the -av-/-i- stem suffix, which is determined by the conjugation). Defaults to the infinitive stem. -- full_impf: The full imperfect stem missing only the endings (-a, -as, -am, etc.). Used for verbs with irregular imperfects such as ser, ter, vir and pór. -- pret_conj: Determines the set of endings used in the preterite. Should be one of "ar", "er", "ir" or "irreg". Defaults to the conjugation as determined from the infinitive. When pret_conj == "irreg", `pret` is used, otherwise `pret_base`. -- pret_base: The preterite stem (not including the -a-/-e-/-i- stem suffix). Defaults to the infinitive stem. Only used when pret_conj ~= "irreg". -- pret: The full preterite stem missing only the endings (-ste, -mos, etc.), e.g. 'fige', 'fo'. Only used for verbs with irregular preterites (pret_conj == "irreg") such as facer, poder, traer, etc. The pret_1s and pret_3s are handled using the short_pret stem instead (pret_1s '-en', pret_3s '-o'). Defaults to `pret_base` + the conjugation vowel. -- short_pret: The short preterite stem, used with 1s and 3s endings (pret_1s '-en', pret_3s '-o'). Only used with irregular preterites (pret_conj == "irreg"). Normally derived from pret by deleting the final vowel, and doesn't	 need to be given explicitly. -- fut: The future stem. Defaults to the infinitive stem + the conjugation vowel. -- cond: The conditional stem. Defaults to `fut`. -- impf_sub: The imperfect subjunctive stem. Defaults to `pret`. -- fut_sub: The future subjunctive stem. Defaults to `pret`. -- plup: The pluperfect stem. Defaults to `pret`. -- pers_inf: The personal infinitive stem. Defaults to the infinitive stem + the conjugation vowel. -- pp: The masculine singular past participle. Default is based on the verb conjugation: infinitive stem + '-ado' for -ar verbs, otherwise infinitive stem + '-ido'. -- short_pp: The short masculine singular past participle, for verbs with such a form. No default. -- pp_inv: `true` if the past participle exists only in the masculine singular. ]=]
