>Ê with the circumflex accent marks an “e” after which originally some other letter was written (usually an S), but this letter is no longer present in its modern spelling.

>By imagining “es” instead of “ê”, we can often deduce the meaning of unknown words; for example, forêt = forest, fête = “feste” = fest(ival); intérêt = interest and many others. The circumflex accent is used in the very same sense also for other vowels, for example île = isle, hôte = “hoste” = host, hâte = haste.
I will always remember this, thanks to my high school French teacher who, knowing her audience, gave us a few examples like "hôpital," and then said "So you can probably guess was 'bâtard' means..."
It comes from Latin fenestra. People are throwing around lots of languages in this subthread, but it needs to be said that the circonflex indicates an omitted s from the Latin original.
Maybe there are cases where the original isn't Latin, but I've never noticed one, and French does not have many words of non-Latin origin. I'm not sure if English speakers commonly know that, but English is a rare case of thoroughly mixed origins.
