"피곤하다"

Translation: tired

[Linda105503]

i put to be tired and was counted wrong when in fact this is the infinitive verb form

[SayJS22]

In a previous one it said 피곤해요 was tired. I'm wondering if it's right that that would be "I am tired" and 피곤하다 is the actual verb 'to be tired'?

Wonder if this is related to Chinese 疲倦 pi-juan.
