More annoying words from Bryson:
Factious, Factitious: Factious applies to factions and thus refers to something that promotes internal bickering. Factitious applies to that which is artificial, such as applause for a despotic ruler. Neither should be confused with fractious, a terms for something disorderly or unruly.
Feasible does not mean probable or plausible, as is sometimes thought, but rather capable of being done. An action can be feasible without being either desirable or likely.
Flammable and Inflammable mean the same thing; the root of inflammable is "inflame"; flammable was invented in the 20th century because too many people thought they "in" meant "not" as in incombustible (something that WON'T burn).
Fulsome is one of the most frequently misapplied words in English. The sense that is usually applied to it -- that of being abundant or unstinting -- is almost the opposite of the word's historic meaning. Fulsome is related to foul and means odious or overfull, offensively insincere.
Habits: customary habits, or usual habits are redundant phrases.
Home, Hone: Hone means to sharpen, home means to seek out a target.
Iterate, reiterate: because reiterate means to repeat, many people assume iterate means simply to state; in fact iterate also meas to repeat. On another point again is always redundant with re- words (reaffirm, repeat) and should be deleted.
