Foresight

Foresight (Q. apacen) is a gift or power apparently given to picked Elves and Men. Many elves appear to have varying amounts of foresight, while some of the more noble men (Númenóreans/Dúnedain) appear to have degrees of foresight on special occasions. In turn, the Númenóreans credited the Drúedain with a "strange foresight" .
Elven mothers would give their children a name, known as essi apacenye or just apacenye, having insight into the characters and abilities of their children, and many also had the gift of prophetic foresight.
Before dying Gwindor had the foresight that if Túrin managed to save Finduilas, she would save him from the Curse of Morgoth. Túrin, however, came too late, and the loss of Finduilas enabled him to meet Níniel much later, and follow his dark fate.
On Númenor the Drúedain were noted for their "strange foresight"; already since the time of Aldarion they felt the land "unstable under their feet", millennia before the Downfall of Númenor, and gradually abandoned it to return to Middle-earth. By the time of the Downfall, they all had left the island.
Dírhael and his wife Ivorwen, grandparents of Aragorn, were gifted in foresight and had premonitions about Arathorn II who wanted to marry their daughter. These premonitions were a reason at first to oppose the marriage, but later to concede to it.
There are several mentions of Seers or Prophets namely Amnon, Glirhuin and Malbeth. Foresight was also seen in dreams: Frodo Baggins saw prophetic dreams during his adventure, and Boromir and Faramir saw a puzzling dream, prompting Boromir to travel to Rivendell to seek counsel.
