Final answer:
The answer is a sonnet, a short poem that typically consists of fourteen lines and presents the deep thoughts or strong feelings of a single speaker in a contemplative manner.
Step-by-step explanation:
The term used to describe a short poem that expresses strong feelings or thoughts of a single speaker in a meditative manner is a sonnet. Sonnets traditionally consist of fourteen lines and contain a turn in thought known as a volta. By contrast, a haiku is a Japanese form that captures nature or seasons within three unrhymed lines using a 5-7-5 syllable pattern, which may also express meditative thoughts but is not defined by the expression of strong feelings or complex thoughts that characterizes sonnets. A ballad typically tells a story in a musical or rhythmic manner, and an epic is a long narrative poem about heroic deeds.
