DERIVATIONder.spa.plural-por-terminacion

the plural class follows from the final segment

A noun ending in an unstressed vowel adds one segment, a noun ending in a consonant adds two, and the choice is predictable rather than stored.

Two of the three plural classes are computed, not stored: the ending of the singular decides which segment is added, and a speaker meeting a new noun knows its plural without being told. That is what separates this dimension from gender, where the value has to be learned with the word. The two computed classes exhaust the ordinary cases. The residue is the class whose plural is identical to its singular, and it is a genuine residue rather than a third rule, because the predictable rule does have an output for those words and the language does not use it.

Premises

derivation.premises

What has to be true for this chain to run. Roughly half of a chain's premises are other derivations, so a premise is often itself a chain.

A noun ending in an unstressed vowel adds one segment, a noun ending in a consonant adds two, and the choice is predictable rather than stored.

Premises (2)

  1. 1pluralizaciónA noun, adjective, determiner or pronoun is used with plural reference, or stands in a dependency on something that is.

Conclusions (3)

derives 2 of 3enumerated

Nouns whose plural is identical to their singular, where the predictable rule would produce a form the language does not use.

Residue (1)

  • CLASSplural invariableunstatedno failed premise is named, so this row records that the case is not covered without recording why

Premises and conclusions declare no order (A16); listed alphabetically by id, a display choice and not a claim about which matters most. The steps above them are the one part of this component that IS a declared sequence, read from the applies-to composition chain.

Conclusions

derivation.conclusions

What the chain establishes. This is a set rather than a single fact: 45 percent of sampled derivations conclude about several things at once, and the several-ness is the claim.

Coverage, and what it does not reach

derivation.coverage

The arithmetic half is a required field and the build checks it. The residue rows are the structured half of the same statement.

Nouns whose plural is identical to their singular, where the predictable rule would produce a form the language does not use.

Everything joined to this object

One group per typed edge, in both directions. A1b guarantees no object node is an orphan, so this is the whole navigation: an object with no edges would have failed the build rather than reached this page.

What this object is a kind of

Walking this object's own `is-a` edges: what it is a kind of. Several branches from one object are several classification axes, not competing supertypes.

None in this view. This subgraph happens to be a tree, which the explorer draws as one without assuming it is one.

Siblings are listed by name, then by id to break ties. That is a display choice made here and not an order the graph asserts.

Fan-out per dimension

A4

One row per dimension, largest first. That is a display order, not a verdict: 03-schema.md declares no threshold above which fan-out is too much, so this reports the count and grades nothing.

What kinds of this object there are

Walking the `is-a` edges that point at this object: what kinds of it there are. An object reachable two ways is drawn in both places and is still one object.
