Incuba (Nightmare)

[Brian M. Scott]

LT> Splendid, and many thanks.  I couldn' find this form in even the biggest
LT> Latin dictionaries in our library, but I don't think they cover
LT> medieval Latin.  As for the chronology, I would like the word to have
LT> entered Basque by about the 11th century, in order to allow that /k/
LT> to undergo the regular voicing after /n/.

Latham's Revised Medieval Latin Word-List (OUP 1980) has <incuba>
'nightmare, demon' in British and Irish sources between 1250 and
ca.1362; however, the form <incubus> is listed as being of regular
occurrence between ca.1160 and 1528.
