Learning adjectives in Thai, a Tai-Kadai language spoken primarily in Thailand, is essential for effective communication. In Thai, adjectives (คำคุณ – kham khun) describe or modify nouns and follow specific grammatical rules. Here’s a detailed lesson on Thai adjectives and their grammatical rules, including transliterations for pronunciation help:

Understanding Thai Adjectives

Thai adjectives provide descriptive information about nouns. Examples include:

• ใหญ่ (yài – big)
• เล็ก (lék – small)
• สวย (sŭay – beautiful)

Position of Adjectives

In Thai, adjectives follow the noun they modify, which is different from the order in English:

• บ้านใหญ่ (bâan yài – big house)
• ดอกไม้สวย (dòk mâi sŭay – beautiful flower)

Agreement in Gender, Number, and Case

• Gender Agreement: Thai does not have grammatical gender, so adjectives do not change form based on the gender of the noun.
• Number Agreement: Adjectives in Thai generally do not change form for plural nouns.
• Case Agreement: Thai is not a case-inflected language, so adjectives do not change form for different cases.

Comparative and Superlative Forms

• Comparative: Formed using “กว่า” (gwà – more than). E.g., ใหญ่กว่า (yài gwà – bigger than).
• Superlative: Often expressed using “ที่สุด” (thîi sùt – the most). E.g., ใหญ่ที่สุด (yài thîi sùt – the biggest).

Adjective Negation

To negate adjectives in Thai, “ไม่” (mâi) is used:

• ไม่ใหญ่ (mâi yài – not big)

Reduplication for Emphasis

Reduplication of adjectives can be used for emphasis or to convey a higher degree:

• เล็กๆ (lék lék – very small)

Practice and Usage

Regular practice forming sentences with adjectives, focusing on their correct placement after the noun and understanding how they modify nouns in different contexts.

Common Mistakes

• Misplacing adjectives before the noun.
• Applying gender and number agreement rules from other languages.
