Well, here's a big one:
How can we fail to spot one of those?
We can have a jumbo portion of chips (though it's not recommended unless it's a really special occasion):
(these are, obviously, not USA chips)
or a jumbo pack of washing powder or cornflakes or sawdust.
Then there are jumbo jets:
A jumbo can be a Dutch or South African shop, too: or a Laosian rickshaw; a US tank; a German glider; or a Pittsburgh sausage.
The most important jumbo to spot, however, is always mumbo jumbo, which is nonsense pretending to be either magic, or something very else important indeed.
Spot the frippet: jumbo. Mumbo jumbo probably comes from the Mandingo mama dyumbo, which is the name of a god. The other jumbos are named after Jumbo the elephant:
Jumbo (1861 -1885) was born in Mali, and spent time in zoos in Paris and London, eventually being sold to PJ Barnum who took Jumbo to America with Barnum's travelling circus.
