If an armada is looking for you, that's not good news — it's a fleet of warships.
Even though armada sounds a little old-fashioned, they still exist. In fact, some armadas look for pirates — another old-fashioned-sounding group that still exists. Though an armada is part of a navy, armada sounds similar to "army,", and it should: they both come ultimately from the same source, the Latin word armata, "armed." Armies and navies are two of the oldest branches of a military power, and an armada is a military fleet — another word for a group of boats or ships.
