Necessary properties vs. essential properties?

[Philo]

Philo, and 1's&0's, elaborate please?

It seems that if someone (me) has no frame of referance as to the OP the answer is, 'no/symantics riddle'.

Some thinking from those that seem to believe they know the answer please...?

If p has a property necessarily then it is not possible for p to not have that property. In other words, in any possible world p has that property.

If p has a property essentially then p cannot exist without having that property. For p to lose that property is for p to cease to exist.

The philosophical issue is certainly not a question of semantics, but again, the traditional answer has usually been yes.

See Kripke's Naming and Necessity and "Identity and Necessity."
