Final answer:
An 'incomplete foot at the end of a line' refers to a poetry line that doesn't end with a complete metric foot, which affects the rhythm and could be a stylistic choice like enjambment.
Step-by-step explanation:
The term 'an incomplete foot at the end of a line' is most likely referring to a line of poetry that does not fully complete its metric foot. In poetry, lines are formed by units of rhythm called feet. A foot is a combination of stressed and unstressed syllables. Examples of different types of feet include the iamb, trochee, dactyl, and anapest. Lines of poetry can have varying numbers of feet, typically ranging from one to eight, with each line named for the number of feet it contains (e.g., a line of one foot, a line of two feet, etc.). If a line is described as having an incomplete foot, this means that it does not end in a complete metric unit, possibly for stylistic effect such as enjambment, where a sentence or clause runs onto the next line without a pause. Understanding the arrangement of feet in a poem is important for analyzing the poem's rhythm and flow.
