User:Erutuon/Ancient Greek interlinear glossing

Issues:
 * Verb stems carry some of the inflectional information that is carried by the ending: λέγ- in λέγει carries the information "present", while -ει carries the information "third-person singular present indicative active" (or arguably "present or future"); ἔβαλλ- in ἔβαλλε carries the information "aorist indicative active", while -ε carries the information "third-person singular aorist indicative active" (or arguably "aorist or imperfect or perfect").
 * Verbs have information for as many as five inflectional categories. Perhaps it is easiest to treat indicative and active as the defaults for the categories of mood and voice, and omit them. Then, εἰμί is "first-person present" and not "first-person present indicative" or "first-person present indicative active".
 * The augment can perhaps be analyzed as a separate morpheme when it is ἐ-, as in ἔλεγον, in which case it probably carries the information "past", or it can be considered a part of the tense stem, in which case it carries the meaning "indicative". When the augment is quantitative, as in ἦγον, it can't be analyzed as a separate morpheme. When there is a prepositional prefix, I am not sure how to format the glossing abbreviations: συνέβην.
 * What was said about the augment is also true of reduplication.

Cases
From Ancient Greek nouns:

Nominative
The Ancient Greek nominative, like the Proto-Indo-European nominative, is used for the subject and for things describing the subject (predicate nouns or adjectives):

Vocative
The vocative is used for addressing people or things. It is frequently the same as the nominative in the singular and always the same in the plural.

Accusative
The accusative is used for the object of a verb, and also after prepositions. After prepositions it is often used for the destination of motion:

Genitive
The Ancient Greek genitive can often be translated with the preposition "of" or the English possessive case:

It is also used after prepositions, especially those which mean "from":

Dative
The Ancient Greek dative corresponds to the Proto-Indo-European dative, instrumental, or locative. When it corresponds to the dative, it expresses the person or thing that is indirectly affected by an action, and can often be translated with the prepositions "to" or "for":

When the dative corresponds to the Proto-Indo-European instrumental, it expresses the thing with which something is done, and can often be translated by the preposition "with":

When the dative corresponds to the Proto-Indo-European locative case (this is often the case when it is used with prepositions), it expresses location (sometimes figuratively) or time, and can often be translated by "in", "at", or "on":

The dative is also frequently used after prepositions, such as ἐν "in":
