Do You buy " GEO / Greek / gem " Names as Domains ?

[fourwings]

Does Geo domains means country names or states names ?.
Does it have value as it represents a country, and not a product or service ? who will be the buyer of such domains ?

Do we register " Greek " words as domains ?
Is it possible to sell those domain names [ i dont know the meaning of the greek words ]

similarly do we register names of gems / semiprecious gems / stars / persons / spain / dutch names as domains ? how is their resale potential

rarely i find one / two if i search for hours that too not sounds sweet. even then i have some craze on one word.

I wish my friends to give some advice on this

Good Luck
