IPA: /ˈhɑːrtˌsɪk.nəs/
KK: /ˈhɑrtsɪk/
The feeling of deep sadness or emotional pain, often due to love or loss.
After the breakup, she felt a deep heartsickness that was hard to shake off.
Heartsickness is formed from "heart" (from Old English "heorte", meaning the organ that pumps blood and also symbolizes emotion) and "sickness" (from Old English "sēoc", meaning ill or unwell). The word describes a state of emotional distress or longing, often associated with love or loss, that affects one's heart.
Think of the heart as the center of emotions, and when someone feels 'sick' from love or loss, it leads to heartsickness.
