prognostises

Prognostises is the third-person singular present tense form of the verb prognostise, used primarily in British English. The verb means to forecast or predict the likely outcome of a situation, often drawing on data, patterns, expert judgment, or models. It is closely related to the noun prognostication and to the verb prognosticate, but prognostise and its third-person form are more common in British spelling.

Etymology and related terms: prognostise derives from the same root as prognosis and prognostication, with the prefix pro- meaning before and the Greek gnosis meaning knowledge. In modern usage, prognosticate is often preferred in American English, while prognostise appears as the preferred spelling in many contexts in British English. The noun forms include prognosis (expected course and outcome) and prognostication (the act of forecasting), while prognostic and prognostically describe related concepts or perspectives.

Usage and nuance: prognostises is used when describing someone who forecasts outcomes, particularly in formal or technical writing. It is common in medical, meteorological, financial, and risk-assessment contexts to discuss predicting disease progression, weather events, or market developments. However, prognosis remains the standard noun for the expected outcome in medicine, and prognosticate is frequently used in more general or American contexts. As with any forecast, statements involving prognostication carry uncertainty and should acknowledge limitations and confidence levels.

Limitations: prognostication relies on models, data quality, and assumptions. Predictions may be revised as new information emerges, and the term remains one tool among many for communicating anticipated futures in professional discourse.
