===Adjectives and adverbs===
There is no general distinction between adjectives and adverbs, and words of this category serve both functions and can even modify each other. Duplication is used to indicate greater intensity. Only one word can be duplicated per phrase. Adjectives always come after the noun they modify; adverbs may come before or after the verb depending on the word. There is usually no copula to link a noun to an adjective.
* เด็กหนุ่ม (dek num) {{IPA|/děk nūm/}} ''A young child.''
* เด็กหนุ่ม ๆ (dek num num) {{IPA|/děk nūm nūm/}} ''A very young child.''
* เด็กหนุ่มที่ไว้ (dek num thi wai) {{IPA|/děk nūm tʰīː wȁj/}} ''A child who becomes young quickly.''
* เด็กหนุ่มที่ไว้ ๆ (dek num thi wai wai) {{IPA|/děk nūm tʰīː wȁj wȁj/}} ''A child who becomes young quickly.''

Comparatives take the form "A X กว่า B" (kwa) {{IPA|/kwáː/}}, A is more X than B. The superlative is expressed as "A X ที่สุด (thi sut) {{IPA|/tʰīː sȕt/}}, A is most X.
* เด็กหนุ่มกว่าผู้แก่ (dek num kwa phukae) {{IPA|/děk nūm kwáː pʰùː.kɛ́ː/}} ''The child is younger than an old person.''
* เด็กหนุ่มที่สุด (dek num thi sut) {{IPA|/děk nūm tʰīː sȕt/}} ''The child is youngest.''

Because adjectives or adverbs can be used as predicates, the particles that modify verbs are also used.
* เด็กซิหนุ่ม (dek si num) {{IPA|/děk sìʔ nūm/}} ''The child will be young.''
* เด็กหนุ่มแล้ว (dek num laew) {{IPA|/děk nūm lɛ̂ːw/}} ''The child was young.''
