After several hundred years, the Egyptians lost sight of both these meanings and
the picture {illust.} came to stand for a single letter, the letter S. A short
sentence will show you what I mean.
Here is a modern English sentence as it would have been written in
hieroglyphics. {illust.}
The {illust.} either means one of these two round objects in your head, which
allow you to see or it means "I," the person who is talking.
A {illust.} is either an insect which gathers honey, or it represents the verb
"to be" which means to exist. Again, it may be the first part of a verb like
"be-come" or "be-have." In this particular instance it is followed by {illust.}
which means a "leaf" or "leave" or "lieve" (the sound of all three words is the
same).
The "eye" you know all about.
Finally you get the picture of a {illust.}. It is a giraffe It is part of the
old sign-language out of which the hieroglyphics developed.
You can now read that sentence without much difficulty.
"I believe I saw a giraffe."
