The USA is a hard country to get presents for, because you seem to have everything.
But as an Australian, I'd like to give a gift of the word "Fortnight". Fortnight is a word that means "2 weeks". Its a little old fashioned but awfully useful. Its a common word in Australia (and the UK I think) and you can find it in every English language dictionary.
Like "week", fortnight can be used as an adjective. For example, "Fortnightly meeting" - which means "A meeting that takes place every 2 weeks." Unlike "bimonthly meeting", a "fortnightly meeting" is clear and unambiguous. It is also well understood by the rest of the English speaking world.
