Answer:
The theme of Sonnet 116 is love.
Step-by-step explanation:
William Shakespeare's "Sonnet 116" talks of what love is all about. It is not a declaration of love as such, but more of a defining and explanation of what love is and should be.
Sonnet 116 starts with the speaker claiming that love is constant and unchanging, "the marriage of true minds". It transcends the normal levels of human measures and also represents the highest level of an individual's activity. Stating that love is a mental relationship that involves truth and fidelity, "a guiding star to lost ships". It is immune to any of the personal, emotional impediments that humans have or made up, not susceptible with time. Though a person's physical features may fade with time, true love never changes irrespective of time. Such is the power of time, capable of keeping time frozen or still.
