thés

Thés is masculine in French. While the etymology tracing it back through Portuguese "chá" to Chinese "chá" (茶) is plausible, the explanation for its masculine gender is speculative and misleading. In French, "thé" is masculine, but this is not exceptional—many French nouns ending in -é are masculine (e.g., "café", "blé", "été"). The word likely retained or was assigned masculine gender because of this productive suffix pattern in French rather than because it was treated as an exotic noun. The rule oversimplifies gender assignment by suggesting loanwords are unpredictable when French morphological patterns actually provide a clear explanation.
