Excessively for Exceedingly. "The disease is excessively painful." "The weather is excessively cold." Anything that is painful at all is excessively so. Even a slight degree or small amount of what is disagreeable or injurious is excessive—that is to say, redundant, superfluous, not required.
Executed. "The condemned man was executed." He was hanged, or otherwise put to death; it is the sentence that is executed.
Executive for Secret. An executive session of a deliberative body is a session for executive business, as distinguished from legislative. It is commonly secret, but a secret session is not necessarily executive.
Expect for Believe, or Suppose. "I expect he will go." Say, I believe (suppose or think) he will go; or, I expect him to go.
Expectorate for Spit. The former word is frequently used, even in laws and ordinances, as a euphemism for the latter. It not only means something entirely different, but to one with a Latin ear is far more offensive.
Experience for Suffer, or Undergo. "The sinner experienced a change of heart." This will do if said lightly or mockingly. It does not indicate a serious frame of mind in the speaker.
Extend for Proffer. "He extended an invitation." One does not always hold out an invitation in one's hand; it may be spoken or sent.
Fail. "He failed to note the hour." That implies that he tried to note it, but did not succeed. Failure carries always the sense of endeavor; when there has been no endeavor there is no failure. A falling stone cannot fail to strike you, for it does not try; but a marksman firing at you may fail to hit you; and I hope he always will.
Favor for Resemble. "The child favors its father."
Feel of for Feel. "The doctor felt of the patient's head." "Smell of" and "taste of" are incorrect too.
