liitude

Liitude is a neologism used in informal discourse to denote a quality or state associated with liquid-like behavior or adaptability. There is no widely accepted definition in established disciplines, and usage varies by field.

Etymology and usage are uncertain; the term appears to be a portmanteau combining elements of liquidity with -itude, a suffix used to form nouns denoting a state or quality. Its origin seems internet-based and not tied to a formal field.

In materials science, liitude is sometimes described as a dimensionless parameter representing a substance's tendency to exhibit liquid-like flow under stress, similar to fluidity. In finance, it has been used to describe the resilience of market liquidity—the ability of markets to absorb shocks without large price gaps. In systems theory, it is used metaphorically to describe adaptability and the capacity to reconfigure states smoothly.

Because there is no consensus, there is no universal method to quantify liitude. Proxies vary by domain: viscosity or diffusion for materials; bid-ask spreads, depth, and turnover for markets; entropy or state-space measures for complex systems. The lack of standardization invites ambiguity and can obscure precise communication, leading some observers to discourage use outside exploratory or fictional contexts.
