Commonly confused words

English is widely regarded as having become the global language and is the dominant international language in communications, science, and business. You would think that with English being so prominent in arenas of logic and commerce, that it would be concise, precise, and devoid of ambiguity. Nothing could be farther from the truth. As Doug Larson stated: “If the English language made any sense, a catastrophe would be an apostrophe with fur.”
