Tsakonian adjectives agree with the noun they modify in gender, number, and case — that is, their endings change to match those of the noun. Tsakonian adjectives are classified into several types based on their gender-specific endings and declension patterns. This section is primarily based on the systematic tables provided by (García Chaparro, 2023).

For the case and gender system used in the table headers, see 5.1 Nouns. For the overall grammar structure, see the 5. Grammar index.
