Examples: Using old words to form a new one
1.
Shakespeare invented verb "articulate" (from the Latin word articulus, 'an article or condition in a covenant') to express concisely 'enter into articles;' and "articulated," to express 'set forth in articles.'
Example:
These things, indeed, you have articulated,
Proclaim'd at market-crosses, read in churches. -- Henry IV, Part I, v. 1.
2.
From the word "trenchant," 'cutting,' Shakespeare has formed the epithet "intrenchant," to express 'incapable of being cut.'
Example:
As easy may'st thou the intrenchant air
With thy keen sword impress, as make me bleed. -- Macbeth, v. 7.
3.
Here the word "plantage" is invented to express plants generally or collectively, all that is planted, vegetation.
Example:
As true as steel, as plantage to the moon. -- Troilus and Cressida, iii. 2.
4.
From the Latin word rubeus, 'ruddy,' and from the gem called 'ruby,' Shakespeare devised the exquisite word "rubious" to convey the sense of 'ruddy,' 'ruby red.'
Example:
Diana's lip is not more smooth and rubious. -- Twelfth Night, i. 4.
