I own two spanish dictionary words one obscure and one more used, the obscure one receives more visits than the known one. I have tried to sold them but no interested yet.
Spanish is my mother tongue and I can assure you that it is one of the most obscure words in my language, it is used only on specific scientific classes on the school-high school or plants related professionals but no one else uses it.
Being an infinitive verb perhaps help but it definitely has not any commercial use I can see on first sight and that is the reason why none of the other extensions is taken.
The domain is reg if lucky otherwise $0, perhaps a collector of Spanish verbs could pay up to $15 but do not expect more. If just registered ask for a refund ASAP.
