* **Language:** Specifies the language of the dictionary terms; automatically set for typo handling dictionaries and user-selectable for stop word and synonym dictionaries.
* **Type:** Automatically set to Spell Check (typo handling), Stop Word, or Synonym, reflecting the dictionary's purpose.
* **State Management:** Tracks dictionary status as New, Draft, or Published to manage lifecycle and publishing of changes.
* **Case and Punctuation Sensitivity:** Options to enable case or punctuation sensitivity for dictionary terms, affecting how terms are matched during search.
* **Derived Entries (Typo Handling only):** Ability to auto-derive typo correction terms from indexed content sources, keeping the dictionary up to date based on actual content.

## Derived Settings for Typo Handling Dictionaries

* **Indexed Sources:** Select indexed data sources from which typo corrections are derived.
* **Auto Refresh:** Defines how often (minimum 24 hours) derived typo corrections are refreshed automatically to maintain accuracy.
* **Blocked Fields:** Allows excluding specific fields or entire tables from derivation to avoid incorrect or irrelevant auto-corrections. Supports notation such as asterisk () for all fields, field names, or table.field formats.
