Plain English Meaning
When something you once learned slowly slips away because you haven't used it for a while.
Full Definition
The gradual loss of previously learned knowledge or skill over time when it is not used, practiced, or reinforced. In learning theory, fading is one of the recognized causes of forgetting and reflects the natural weakening of memory traces that are not periodically recalled or applied.
Context Anchor
Used in flight and ground instruction when an instructor first gives close guidance, then slowly steps back as the student becomes more capable.
Derivation
From the Old English 'fadian,' meaning to grow weak or lose color. The image is of something once vivid that gradually becomes faint — useful here because it captures how a skill or fact doesn't disappear all at once, it just quietly weakens with disuse.
