Alone which means unaccompanied should be distinguished from only which means no other.

Alternative should never be used in speaking of more than two things.

Altogether is not the same as all together.

Among should not be used with one another, e. g., "They divided the spoil among one another." It should be "among themselves."

And should not be placed before a relative pronoun in such a position as to interfere with the construction. It should not be substituted for to in such cases as "Try and take more exercise."

And which should not be used for which.

Another should be followed by than not from, e. g., "Men of another temper from (than) the Greeks."

Answer is that which is given to a question; reply to an assertion.

Anticipate should not be used in the sense of expect. It means "to forestall."

Anxious should not be confused with desirous. It means "feeling anxiety."
