Looking into a dictionary entry for last, I come up with:
1) Final, ultimate, coming after all others of its kind.
2) Most recent, latest, last so far.
Looking up final:
1) last; ultimate
2) Conclusive; decisive
Now I'm wondering what's the difference between final decision and last decision, were one to be strict and pedantic.
last decision - ambiguous - may mean "final decision" or "most recent decision in a chain of decisions yet to follow
final decision - not ambiguous - means only "final decision"
Am I correct here or am I somehow mistaken?
