CONSTRUCTIONcon.spa.deber-infinitivo

perífrasis de obligación con deber

A two part predicate stating that the subject ought to bring the event about, the requirement coming from a rule or from the speaker.

The construction states a requirement grounded in a rule, a duty or the speaker's judgment, which is what separates it from the pattern whose requirement comes from circumstances. It joins the two verbs with nothing between them, which is unusual in its family and is the point on which it is distinguished from the inferential construction built on the same auxiliary. In the conditional it softens to advice without ceasing to be a requirement, and that softening is regular enough across the modal family to be a property of the conditional rather than of this construction. It is the modal at home in written and formal registers, where the circumstantial obligation pattern is less usual.

Why this is a construction at all

construction.admission

Goldberg's admission test: a template earns storage either by being unpredictable or by being frequent.

admissionadmission
frequentit is stored because it recurs often enough to be learned whole

The slots

construction.slots

At least two, by the schema: fewer is not a multi-element template. Every filler is a link, never a name in prose.

Confusable with

construction.confusable

Objects a reader is likely to mix up with this one, and the difference that separates them. The edge is symmetric and stored once, so this renders on both objects' pages from the one statement.

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.
