the unillustrable ABC

There are lots and lots of ABC books for kids (A is Apple, B is for Bear) ranging from the mundane to the clever. But what about an ABC book where all the words would be difficult or impossible to draw?

I'm still missing a few words, but here's a start

A abstract

B biodegradable

C common, coincidence

D disappear

E evanescent

F foreign

G gone

H hidden

I ineffable (or invisible)

J

K

L lost

M more

N never, nowhere, none

O obvious

P

Q

R reverse, random

S somewhere, sublime

T temporary

U unusual

V virtual, vanish

W why

X

Y

Z zero

It would be cooler if all the words were likely to be in a four year olds vocabulary.
In this version, only "why" and "more" fit that criteria.
