A Sonnet is a poetic form that traditionally consists of 14 lines, typically written in iambic pentameter. There are several types of sonnets, with the most common being the Shakespearean (or English) sonnet, which features three quatrains followed by a couplet, and the Petrarchan (or Italian) sonnet, which consists of an octave and a sestet. Sonnets often explore themes of love, nature, and beauty, and they adhere to specific rhyme schemes. Their structured format allows poets to convey complex emotions and ideas within a concise framework.
