Answer:
Enjambment is (in verse) the continuation of a sentence without a pause beyond the end of a line, couplet, or stanza.
Explanation:
As per my understanding of "Birthplace" by Tahereh Saffarzadeh, the term enjambment refers to the continuation of verse from one line of a poem to the next without a syntactical interruption.
In a poem enjambment lines usually do not have a punctuation mark at the end and is running on a thought from one line to another without final punctuation. It is used in poetry to trick a reader. Poets lead their readers to think of an idea, then move on the next line, giving an idea that conflicts with it.
Each enjambment line in a poem does not have to be a full sentence. The thought or syntactic unit does not have to be all in one line. Enjambment occurs when a poet breaks the normal beat and continues the meaning to another line
