The term "Fighter"

What does it mean nowadays with the introduction of multirole fighters
.. Does it mean :

(1) An aircraft tasked with destroying other enemy aircraft ie Tornado
F.3

(2) An aircraft that is tasked with destroying enemy military hardware
including: SAM sites, AA Guns , tanks and other aircraft on the ground
or in the air IE most of the USAF/USN fastjet tactical inventory with
the exception of the A-10

Has the term become diluted over the years to mean an aircraft that
can destroy most GENERAL militery hardware?
