ETYMOLOGY & EXAMPLE
E-CEN lists EFFRAYABLE with the etymology, from effray + -able
E-HUN lists EFFRAYABLE, EFFRAIABLE with the etymology, from French effrayable
E-BAI (1675 edition) lists EFFRAIABLE with the etymology, from French effroyable
E-NED only lists EFFROYABLE, and EFFRAJABLE which it suggests is a misprint for EFFROYABLE
The only example given for the word is from Gideon Harvey's 'Advice Against the Plague.'
E-NED however shows 'effrajable'

Other dictionaries show 'effraiable' - the following is from E-HUN

I was unable to find an example of the passage from the book earlier than Johnson's 1773 edition, let alone find the 1665 book to compare the word.
(Note the different endings of the two examples)
So, which is it - effrayable or effroyable?
(E-NED is the only dictionary listing 'effroyable')
Until I can find any further examples, I'm staying with EFFRAYABLE for the time being,
as I think it's quite possible that E-NED's 'effrajable' could be a misprint for ''effraiable'.
Any comments, further reference, etc. on this word would be greatly appreciated.
