Usage Note
Antinatural is an invariable adjective — it does not change for gender, only for number (antinaturales). It can carry a moral or ideological charge depending on context; learners should be aware that the word is often used in debates about social norms, so its use can feel loaded. A more neutral option is poco natural or forzado.
Examples
"Su comportamiento era completamente antinatural."
Natural Translation
His behaviour was completely unnatural.
