means The practice of forming a mental picture of something — often a goal or outcome — in vivid enough detail that your mind starts treating it as real.

from Built from 'visual' (Latin 'visus,' seen, from 'videre,' to see) plus the noun-forming suffix '-ization,' meaning 'the act or process of making.' So, literally, 'the act of making something seen.' The word itself is a 19th-century formation, part of a wave of English coinages that bolted '-ize' and '-ization' onto older roots to describe new mental and industrial processes — the same pattern that gave us 'standardization' and 'modernization.' Its leap from a neutral term for mental imagery into self-help and sports-psychology jargon is a much later, 20th-century development.
