What does condensational mean?
'Condensational' is a technical adjective describing anything related to condensation — the physical process by which a gas or vapour turns into a liquid. It appears almost entirely within scientific writing rather than everyday language, and its most prominent home is atmospheric science, where phrases such as 'condensational heating' and 'condensational growth' describe how latent heat released by condensing water vapour drives storms, and how cloud droplets enlarge by drawing vapour from the air. The word derives from the Latin root densus ('thick, dense'), via the verb condensare, 'to make dense', which also gave English 'condense' and 'condensation'. Because it is so specialised, general readers rarely encounter it; when they do, it signals a precise, scientific register. For anyone studying weather, clouds, or phase changes, however, it is a compact way of attributing an effect specifically to condensation rather than to other processes such as evaporation or deposition.
adjectiveRelating to or involving condensation, especially the change of a substance from vapor to liquid; in atmospheric science, describing processes or effects caused by the condensation of water vapour.
- Relating to condensation generally, i.e. the conversion of a gas or vapour into a liquid state.
- Specifically describing processes or effects arising from the condensation of atmospheric water vapour, as in meteorology and cloud physics.
"The model showed that condensational heating in the storm's core intensified the updraft."
"Cloud droplets enlarge mainly through condensational growth as water vapour deposits onto existing particles."
"The study quantified how condensational warming aloft contributes to the deepening of extratropical cyclones."
You won't meet 'condensational' in casual chat, but climate scientists rely on it daily — 'condensational heating' is literally the engine that powers hurricanes and thunderstorms.

Etymology of condensational
Condensational is formed from the noun 'condensation' plus the adjectival suffix '-al', placing it among English words built by regular derivation in the early modern period. The underlying Latin root is densus, meaning 'thick' or 'dense'; the derived verb condensare ('to make dense') passed into English via French as 'condense' in the late sixteenth century, with 'condensation' following soon after. The same Latin stock also gave English 'dense', 'density', and 'condenser', making these close relatives of condensational.

How condensational is actually used
A technical, formal word found almost exclusively in scientific literature — particularly meteorology, cloud physics, and aerosol science — rather than everyday speech. Writers more often reach for the plain noun 'condensation' or simply say 'relating to condensation'.
Easily confused with condensational
Condensation is a noun denoting the process or product of turning vapour into liquid, while condensational is the rarer adjective describing things pertaining to that process.
Evaporational describes processes involving evaporation (liquid to vapour), whereas condensational describes processes involving condensation (vapour to liquid).
