K “want” = thelo. Same as “wish” in v23. See note C above.
L “save” = sozo. From sos (safe, rescued, well). This is to save, heal, preserve, or rescue. Properly, this is taking someone from danger to safety. It can be delivering or protecting literally or figuratively. This is the root that “savior” and “salvation” come from in Greek.
M “life” = psuche. From psucho (to breathe, blow). This is breath, the breath of life, the self, individual, soul. This is the word for that which makes a person unique – their identity, will, personality, affections. This isn’t the soul as the immortal part of us, but as our individuality. It is also not life as a general concept, but specific to people. This is where the words psyche and psychology come from.
N “lose” = apollumi. From apo (from, away from) + ollumi (to destroy or ruin; the loss that comes from a major ruination). This is to destroy, cut off, to perish – perhaps violently. It can also mean to cancel or remove.
