How does goneril die?

Answer 1

Goneril is the eldest of Lear's daughters, and thus a few years older than Cordelia, who is of marriageable age. She herself is married, and is not so old as to be past childbearing age (else Lear's prayer that she should be sterile would have no sting). She is also young enough to be involved in an affair with Gloucester's younger son Edmund without eyebrows being lifted about the age difference (or indeed without her suspecting Edmund's motives, but an older woman might allow herself to be flattered by protests of love by a younger man--Queen Elizabeth certainly was).

On the other hand, Lear gives his age as "fourscore and upward" which puts him in his eighties. Had Shakespeare lived to that age, his daughters would have been in their late fifties or early sixties! We can only imagine that Lear had his daughters late in life, which seems a very strange pattern of behaviour for a king in a heritable monarchy. Henry VIII had become panicky when he hit forty and had only one heir. What must Lear have felt if he was childless at the age of fifty?

Nevertheless, this is the only timeline that makes sense of everything. Goneril is probably about 35 years old.

Answer 2

She kills herself because after all the evil she has done in the play she would rather die then apologize.

i think it's because Albany had found out that she had plotted his death with Edmund and emend also passed away.

Answer 3

Goneril stabs herself with a poisoned dagger after killing her sister Regan.

Answer 4

Her sister Goneril poisons her. They are fighting over Edmund and Goneril must think that Regan, being unmarried, has the better chance.
