What does TAX mean?

 Here are some of the answers I received online when I asked that question:

TAX...
... is what someone from Yorkshire uses to chop twood.
... means to add something to a taxonomy.
... is annoying little nails that keep the carpet down.
... means 'Many thanks' in Danish.
... is the verb for using a taxi.
... means Taken Abroad EXclusively: the new way to get the Capital of England to the Cayman Islands
... is something to be avoided at all costs.

And, finally, my absolute favourite:
TAX can be shown to be a cheeky government joke: 'Tax' is made up of the word 'Ta', followed by a little kiss. "Thanks for yer money, suckers"
