Is the word adorava the same in Brazilian and European Portuguese?

No

While the spelling and the primary definition of "adorava" (the imperfect indicative of the verb adorar) are identical in both dialects, there is a significant difference in typical usage and pronunciation.

In Brazil, "adorava" is frequently used colloquially as a substitute for the conditional tense (adoraria) to express a polite wish, a desire, or a hypothetical situation (e.g., "I would love it if..."). In Portugal, while the word can be used for past habits, the conditional "adoraria" is much more standard for expressing wishes, and the verb "gostar" (in the imperfect "gostava") is often preferred for polite requests.

Regarding pronunciation, Brazilian Portuguese tends to have more open, audible vowels. In Continental Portuguese, unstressed vowels are often reduced or "swallowed," meaning the "a" in "adorava" might sound much more closed or nearly silent to a Brazilian ear.
