I was laying in bed last night dwelling on the semantics of why sometimes past tense verbs are used in common expressions about ongoing states. Three come to mind:
お腹が空きました ‘I’m hungry’
疲れた ‘I’m tired/worn out’
のどが渇きました ‘I’m thirsty’
I’m sure others exist, but the three that came to mind all apply to the body. I don’t know if that is part of the underlying reason of why the past tense can be used in these contexts, but I was curious what the community thinks about why it is used in these cases.
