Notes on Usage

• In contemporary Vietnamese, "hen suyễn" is the standard and medically precise term for the disease asthma. The standalone word "suyễn" is perfectly understandable but is often used in more informal or colloquial contexts.
• The verb meaning "to deteriorate" for "suyễn" is now rare. The more common verb for this meaning is its root, "suy" (e.g., - health declines).
• The reference context provided ("suy suyễn" meaning "be harmed") appears to be an error or a very obscure/archaic usage. The standard and primary meaning of "suyễn" in modern Vietnamese is related to the medical condition asthma.
