How it's used

This term is specifically used to describe a state of chronic, lingering illness or a persistent, low-grade infection that drains one's vitality. It carries a sense of being 'stuck' in a sickly state rather than suffering from an acute, sudden injury. It is rarely used in formal medical contexts today and is more common in older, colloquial speech or traditional health descriptions.

Examples

He seems to have been chronically ill for a long time, he is always listless.
Are you suffering from a chronic illness? Why do you look so pale?

Common phrases

chronically ill for a long time

Common mistake

Do not confuse this with general sickness like 病. It implies a long-term, draining, or persistent condition rather than a temporary cold or fever.
