You can fill in the blanks to form words that are four syllables, whose first
two syllables are letters of the alphabet, a property that also turns out to be
shared by the title and the answer.

The first letters of the correct answers appear in the set of eight letters at
the bottom of the page. They begin in alphabetical order, but you can re-order
them to match the letters at the bottom. These words are:

ANYbody       = N E
DIES irae     = D S
GEOmetric     = G O
ESTImation    = S T
IMMEdiate     = M E
EFFERvescent  = F R
ALLIances     = L I
EXCEEdingly   = X C

The answer is ESOTERIC.
