For example: Back in the day "Pot" - That which someone cooks in was not used for that which people smoked, and rarely used in socially acceptable circles as that which is collected in a manner of gambling since such was outlawed.
Therefore, it is not unusual to find such as you have given for "nekros." For in the modern (from about the 200AD, philosophies that infiltrated the church, the terms have gradually become modified.
HOWEVER, the term in the purest definition that which is dead, a corpse, or one in which death has been pronounced. It has no "spiritual dead" yet one living definition.
It is not ever used in Scriptures to indicate "spiritually" dead, but ALWAYS applies to one who is condemned - "Dead (nekros) in trespasses and sins." Ephesians. As one considered as already dead, a corpse. They may be breathing, but are in fact dead and worthless except for decay.
Or as Colossians states, "When you were dead (nekros) in your sins and in the uncircumcision of your flesh..."
Or, again in Ephesians, "Even when we are dead (nekros) in sins, hath quickened us together with Christ..." Quickened, is not just a "spiritual" alive, but as the Christ states, "They that believe in me shall never die."
Again, it is ALWAYS pertaining to the physical, unless someone can show specifically what Scripture aligns the "spiritually dead" outside of that person also being "physically dead" using the definition of one "Condemned already" (as our Lord stated of the unbeliever's condition) that is already dead.
