Arcadia

Arcadia is a highly expressive conlang built on consistency and clarity, eliminating exceptions entirely.

Its innovative grammar and syntax, coupled with extreme expressiveness and precision, make the learning curve steep. However, because Arcadia is logical and predictable, with a simple orthography and phonology, a small vocabulary that expands through prefixes, mastery becomes easier once the fundamentals are learned.

Syntax

Arcadia's syntax is designed to be intuitive and flexible. Its standard word order is Verb-Subject-Object (VSO), emphasizing action over actor. However, as a pro-drop language with case markings, word order may shift for emphasis.

Arcadia follows the Austronesian alignment, but not purely; it incorporates elements from other alignment systems as well.

Understanding Syntax through Diagrams

Traditional nominative-accusative languages follow an asymmetric structure. In active voice, the subject is the main actor, the verb conveys action, the direct object receives the action, and the indirect object is the recipient.

graph LR
  A([**Subject**<br/>_John_]) --> B@{ shape: circle, label: "**Action**<br/>_gives_" }
  subgraph objects
    direction TB
    C([**Direct Object**<br/>_the ball_]) --> D([**Indirect Object**<br/>_to Mary_])
  end
  B --> objects

In passive voice, the direct object can be promoted, but the syntax undergoes major changes:

graph LR
  A([**Subject**<br/>_The ball_]) --> B@{ shape: circle, label: "**Action**<br/>_is given_" }
  subgraph recipients
    direction TB
    C([**Agent**<br/>_by John_]) --> D([**Indirect Object**<br/>_to Mary_])
  end
  B --> recipients

Arcadia's Symmetric Syntax

Arcadia's syntax is symmetric, following the Austronesian alignment.

graph LR
  B@{ shape: circle, label: "**Action**<br/>_gives_" }
  subgraph participants
    direction TB
    A([**Actor**<br/>_John_])
    C([**Patient**<br/>_the ball_])
    D([**Recipient**<br/>_to Mary_])
  end
  B --> A
  B --> C
  B --> D

The actor, patient, and recipient can all act as the focus.

Recipient

The recipient here refers to the receiver of the patient, not the action itself.

Subclauses

Arcadia allows an infinite number of nested subclauses, enabling highly expressive ideas.

• Subclauses use the indicative mood, meaning they retain their own subjects.
• Tense is always relative to the preceding clause, ensuring seamless narrative progression.
