A buzzword is a trendy, fashionable, or jargon-heavy term that is often used to impress, persuade, or give an illusion of expertise or innovation, especially in technical, academic, or corporate contexts.

• Vague or overused: Often lacks a clear or consistent definition.
• Contextually inflated: Used more for effect than clarity.
• Signal over substance: Implies sophistication but may obscure the actual meaning.

• biomarker
• personalized medicine
• big data
• artificial intelligence
• neuroplasticity
• disruption
• connectivity anomalies

• Used to inflate the novelty or importance of otherwise weak or ordinary findings.
• Make peer review and comprehension harder by replacing precision with flair.
• Create a false impression of innovation without rigorous evidence.

A buzzword is a word that sounds smart, sells well, but often says little.
