Foreshadowing plants information that gives a later development retrospective inevitability. The target is a narrow one: the reader should not see it coming, but should immediately recognise, once it arrives, that they had everything they needed. Too faint and the ending feels arbitrary; too heavy and the reader is waiting for a development the characters have not reached, which converts suspense into impatience.
Also written as planting and payoff, seeding.
Hide it in another job
The reliable technique is to have the planted information do something else at the time — characterise someone, establish a setting, produce a laugh — so the reader files it as texture rather than as a clue. Information that arrives with no other purpose announces itself, which is why isolated ominous sentences are the least effective form of the device.
Three mentions, decreasing weight
A common working pattern is to introduce the element prominently in a context where it does not matter, refer to it once in passing, then use it. The prominent first appearance means the reader has genuinely met it; the casual second means they have stopped tracking it; the payoff then lands as recall rather than as revelation.
Foreshadowing versus telegraphing
The line is whether the reader can predict the specific outcome. Establishing that a character is a strong swimmer is foreshadowing; having them mention that they always worried about drowning is telegraphing. Beta readers who correctly guess the ending are usually responding to information that had no purpose other than to prepare them for it.
Where to see it working
Rebecca — Daphne du Maurier
The house, the staff's behaviour and the boat are established as texture long before any of them are used.
The Secret History — Donna Tartt
The opening states the outcome, so every planted detail afterwards does characterising work while quietly preparing it.
Never Let Me Go — Kazuo Ishiguro
The vocabulary itself is the planting, so the reader assembles the truth before it is stated and still feels the arrival.
How it goes wrong
Planting information that has no other job at the time, which announces itself as a clue.
Repeating the plant until the reader is waiting for the characters to catch up.
Telegraphing the specific outcome rather than the capability or condition behind it.
Adding the plant in revision without giving it a second, casual mention.
