word - Second-rate spelling

Find the longest word which can be spelled with the second letters of a group words in alphabetical order. An example with incomprehensible (16 letters):

aim
answer
eccentric
fold
implore
ipsilateral
iridium
jester
khaki

leg
one
ostrich
pig
ubiquitous
ulterior
vendetta

In the case of a tie, the winner is the solution whose last word (here, vendetta) comes first in alphabetical order.

Checking a dictionary for words (online or offline) is fine, but no programming or other automated solutions. May the best human win!

Notes (added after several answers):

• No acronyms or abbreviations


• No proper names

n u ll
o d e
o i ntment
o n

p i tt
p t erodactyl
q a t
s t able
t i me
u b iquitous
v u g
y s laked

NOTE: The above is rejected I believe mainly because of kbar - short for kilobar. nth is in wikitionary while zth is not.
