Sonnet, originally invented by an Italian poet named Giacomo da Lentini (Oppenheimer, 1982), is a type of classic poem that is known for its distinctive characteristics: consists of 14 lines, written mostly in iambic pentameter, and has a strict rhyme scheme. Conversely, as sonnets grow its own fame in England during Renaissance, William Shakespeare with his sonnet sequence is considered as one of the most notable (Neely, 1978). Despite the strict tradition in writing sonnets, another matter that is worth-considering is the poetic license, a theory in which an author has the liberty to extricate their writings from language structural rules—committed grammatical error being one of the instance—for the sake of aesthetics. Using the formalist approach, this study aims to seek how Shakespeare used his privilege for his writings' beauty, specifically in Sonnet 116.
