***** NOT A TEACHER *****
(1) The New Oxford American Dictionary defines pizzazz as "an attractive combination of vitality and glamour."
The word may have been coined (invented) by an American fashion magazine in the 1930's.
(2) If I understand your paragraph correctly, those two persons simply walked back to the island on a narrow and
muddy path. Well, getting back to the island by just walking back did not involve any pizzazz (nothing "vital" or "glamorous"
about walking back on a trail or path), but it was very practical. That is, it got them back to the island safely. And that was
what they wanted.
(3) Here's another example: The Times newspaper (of London), which used to be the newspaper of the ruling classes, did
something very big in 1966: it put news on the front page. Until 1966, it had (almost) always put only small advertisements
on the front page. Of course, most people thought that it lacked pizzazz, so they would not buy it. Putting the news on the
front page along with interesting headlines and big photographs gave the paper some pizzazz. (Supposedly!)
(4) Just think of what might have happened if the guy in your paragraph had thought of an exciting and unusual
way to return to the island. Maybe Aislinn would have kissed him! (On the other hand, he could have chosen a
way full of pizzazz but lacking in practicality. So they would never have gotten back to the island!)
P.S. Did you watch on television the Academy Awards from Hollywood last night? Now, that is pizzazz!
