Part of speech: noun

Definitions

1. A mnemonic device or technique used specifically to assist in the memory retention of concepts related to the respiratory system
2. A structured method or strategy for remembering information pertaining to lung functions and breathing principles
3. A memory aid designed to facilitate the learning and recall of topics associated with pulmonary health and respiratory anatomy

Etymology: The memory aid you describe is a "mnemonic," from Greek "mnēmonikos," meaning "concerning memory." That Greek word comes from "mnēmē," memory, and the family goes back to Mnemosyne, the goddess of memory and mother of the Muses in Greek myth. In English, "mnemonic" can be an adjective or a noun for a device that aids recall, and the plural "mnemonics" can mean the techniques themselves. The mix-up probably comes from "pneumonic," which has nothing to do with memory. It comes from Greek "pneumōn," lung, and is related to "pneumonia" and the phrase "pneumonic plague." The two words look alike and share a sound, but they have separate roots. The silent "m" and "n" pattern in "mnemonic" is what gives it its "nemonic" pronunciation, while the "pn" in "pneumonic" is pronounced in full.
