Each is used to denote every individual of a number.
Every denotes all the individuals of a number.
Either and or denote an alternative: "I will take
either road, at your pleasure;" "I will take this or
that."
Neither means not either; and nor means
not the other.
Either is sometimes used for each—"Two thieves
were crucified, on either side one."
"Let each esteem others as good as themselves," should
be, "Let each esteem others as good as himself."
"There are bodies each of which are so small,"
should be, "each of which is so small."
Do not use double superlatives, such as most straightest,
most highest, most finest.
The term worser has gone out of use; but lesser is
still retained.
The use of such words as chiefest, extremest, &c,
has become obsolete, because they do not give any superior force to
the meanings of the primary words, chief, extreme, &c
