Boot

From Wikipedia

A boot is the tall or strong shoe used so your foot won't get wet or get hurt. Some boots are held on with bootstraps or bootlaces. Some also have spats or gaiters to keep water out. Most have the very strong boot sole, the bottom part of the boot.

to "bootstrap"[edit]

People used to make the joke by saying "to lift yourself up by your own bootstraps". This is actually impossible. Now to bootstrap is an idiom meaning "to use something simpler to get something more complex to make itself work better." The word "boot" is also used to say how the computer starts.

"to boot"[edit]

To boot is an idiom meaning also. An example: "he had the beer, and the whiskey to boot." Meaning he had both, and the whiskey after the beer. This is probably related to the bootstrap idiom.
