What does adaptative mean?
'Adaptative' is an adjective describing something capable of adapting — adjusting itself or being adjusted to suit new conditions, whether in organisms, systems, or behaviors. It means precisely what the far more common word 'adaptive' means, and indeed survives chiefly as a variant of that word. In biology, an adaptative trait is one shaped by natural selection to fit an organism to its environment; in engineering or psychology, it describes designs or responses that flex in the face of changing demands. The word derives from Latin 'adaptare', meaning 'to fit or adjust', formed from 'ad-' ('toward') and 'aptare' ('to make fit'), the same root behind 'aptitude' and 'adept'. Though grammatically sound and historically attested, 'adaptative' has been steadily displaced by 'adaptive' since at least the nineteenth century, and most modern style guides and scientific publications favor the shorter form. Writers today encounter it mostly in older texts, though it remains correct and occasionally appears where rhythm or emphasis favors the longer word.

"Engineers praised the material's adaptative properties, noting how it responded to changing loads without failure."
'Adaptative' is a perfectly legitimate word that has spent centuries being quietly outcompeted by its shorter rival 'adaptive' — proof that even words must adapt or fade.

Etymology of adaptative
'Adaptative' comes from the Latin verb 'adaptare', meaning 'to fit, adjust, or make suitable', formed from the prefix 'ad-' ('toward') plus 'aptare' ('to make fit'), itself related to 'aptus' ('fit, suited'). The word entered English as a derivative of 'adapt', likely in the seventeenth or eighteenth century, alongside the competing formation 'adaptive'. Both forms coexisted for centuries, but 'adaptive' gradually became dominant, leaving 'adaptative' as a recognized but increasingly rare variant. Its cognates include 'adaptation', 'aptitude', and 'adept', all tracing back to the same Latin root concerning fitness and suitability.
