Answer :

Let's break down the given table into understandable parts.

### Leyenda Informativa
This part translates various grammatical abbreviations into their full forms in Spanish:

- O: Oración (Sentence)
- SN: Sintagma Nominal (Noun Phrase)
- SV: Sintagma Verbal (Verb Phrase)
- Sprep: Sintagma preposicional (Prepositional Phrase)
- Sadj: Sintagma adjetival (Adjectival Phrase)
- Sadv: Sintagma adverbial (Adverbial Phrase)
- Det: Determinante (Determiner)
- N: Nombre (Noun)
- Vi: Verbo intransitivo (Intransitive Verb)
- Vt: Verbo transitivo (Transitive Verb)
- Vc: Verbo copulativo (Copulative Verb)
- Prep: Preposición (Preposition)
- Adv: Adverbio (Adverb)
- Adj: Adjetivo (Adjective)

### Reescritura según las categorías constituyentes
This part shows how an "Oración" (sentence) can be rewritten using its constituent categories:

- O: Oración can be rewritten as "SN + SV"
- Example: A sentence ("Oración") can be broken down into a noun phrase ("Sintagma Nominal") followed by a verb phrase ("Sintagma Verbal").

The rest of the entries in the reescritura section are left empty, meaning it's a placeholder for further structural definitions which aren't provided in the current context.

Here’s the table completed with provided details:

| Leyenda informativa | | Reescritura según las categorias constituyentes |
|---------------------|--|-----------------------------------------------|
| O | Oración | O [tex]$\longrightarrow$[/tex] SN + SV (ejemplo) |
| SN | Sintagma Nominal | SN [tex]$\longrightarrow$[/tex] |
| SV | Sintagma Verbal | SV [tex]$\longrightarrow$[/tex] |
| Sprep | Sintagma preposicional | Sprep [tex]$\longrightarrow$[/tex] |
| Sadj | Sintagma adjetival | Sadj [tex]$\longrightarrow$[/tex] |
| Sadv | Sintagma adverbial | Sadv [tex]$\longrightarrow$[/tex] |
| Det | Determinante | Det [tex]$\longrightarrow$[/tex] |
| N | Nombre | N [tex]$\longrightarrow$[/tex] |
| Vi | Verbo intransitivo | Vi [tex]$\longrightarrow$[/tex] |
| Vt | Verbo transitivo | Vt [tex]$\longrightarrow$[/tex] |
| Vc | Verbo copulativo | Vc [tex]$\longrightarrow$[/tex] |
| Prep | Preposición | Prep [tex]$\longrightarrow$[/tex] |
| Adv | Adverbio | Adv [tex]$\longrightarrow$[/tex] |
| Adj | Adjetivo | Adj [tex]$\longrightarrow$[/tex] |

Therefore, the solution provides a linguistic legend and suggests the primary syntactical structure of sentences in terms of their constituent syntax categories.
