If “Wealth” is taken as “Private” or individual, and “Commonwealth” be taken in its derivative sense, as “wealth in common,” or, the “public wealth,”‌ then this would be a case of Exclusion. If “Wealth” is taken as the condition of great abundance, and “Commonwealth” as the political body, known as a State, then this is a case of Inclusion by sight, or by sound, the word “wealth” belonging to both alike.

COMMONwealth. UNcommon. } Ex.

Considering “Common” in relation with “Uncommon” we have Exclusion. In the previous pair, we used wealth of commonwealth to make a relation with the simple word wealth. Here we use the first two syllables of the word to contrast with uncommon.

Uncommon. Rare. } Syn. Inclusion.

These words are nearly alike in meaning. Other examples: “Choice, Preference;” “Resolute, Determined;” “Economical, Frugal;” “Ugly, Ill-looking;” “Insane, Mad;” “Lie, Untruth;” “Reliable, Trustworthy;” “Air, Atmosphere;” “Resident, Dweller,” etc.

Rare. Well done. } Ex.

This pair requires careful notice. “Rare” with reference to “Uncommon” means unusual, seldom met, or unfrequent; but considered in reference to “well done,” it means partially cooked or underdone. This, then, is a clear case of Exclusion. Other examples: “Men whose heads do grow beneath their shoulders, and men whose shoulders do grow beneath their heads;” “Cushion, Mule’s Hoof;” “Ungoverned, Henpecked;” “Bed of Ease, Hornet’s Nest;” “Waltz, Breakdown.”

Well done. Badly done. } Ex.

A clear case of Exclusion. They are both “done,” but one is done “well,” and the other “badly done,” or the opposite of well.

Badly done. Good. } Ex.
