I have compiled a list of over 1700 dictionary word .us domains available (according to WHOIS) using the Del.icio.us format. This means that the domain is a word which ends in ‘us’ and that forms part of the word and domain name.

15 of the most interesting are:

1. idolatrous – ido.latro.us
2. incautious – inc.autio.us
3. autotomous – autotomo.us (and au.totomo.us)
4. barbarous – ba.rbaro.us
5. blusterous – bl.ustero.us
6. cadaverous – ca.davero.us
7. calamitous – ca.lamito.us
8. halogenous – ha.logeno.us
9. officious – of.ficio.us
10. outrageous – o.utrageo.us
11. semilustrous – semilustro.us
12. seminiferous – seminifero.us
13. semireligious – semireligio.us
14. slumberous – sl.umbero.us
15. sulphureous – sulphureo.us

PS. This assumes that 2 letter domain names are valid for .us domains.
