Which term is defined as the continuation of a line of poetry to the next line without punctuation or pause? free verse alliteration enjambment assonance

There are notable differences between the literary devices, enjambment, free verse, alliteration and assonance.
An enjambment is a literary device that is primarily used in forms of poetry, in which there is no punctuation or pause between lines. A very good example of the use of enjambment is in a poem, which follows a specific pattern or meter, as in a Haiku, which has seventeen syllables and three lines; with five in both the first and third lines, and seven in the second. If a thought has to be continued from one line to the next, but does not conform to the metric requirement, then it flows to the next one, without punctuation. Here a two examples of Haiku poems, which show the use of no punctuation in some lines. They are from Yosa Buson (1716-1784), a Haiku master poet and painter:

Light of the moonMoves west, flowers' shadowsCreep eastward.
In the moonlight,The color and scent of the wisteriaSeems far away.

A free verse is a non-symmetrical type of poetry that really no rules. It follows no rhythmic pattern, nor has any rhymes or patterns. It is considered modern poetry, but has actually been around for thousands of years.

An alliteration is a form of writing, in which the first syllable in each word begins with the same sound. It is usually found in tongue twisters. Here is an example:

Peter Piper picked a peck of pickled peppers.
An assonance is is a figurative expression, which uses repetition of nearby vowel sounds to convey effect, in either text or poetry. Here is an example by Carl Sandburg, in Early Moon.

“Poetry is old, ancient, goes back far. It is among the oldest of living things. So old it is that no man knows how and why the first poems came.”

These are the differences between the literary devices. An enjambment allows lines to be written without pauses or punctuation marks. A free verse follows no pattern; an alliteration allows all or most of the words to begin with the same sound, while an assonance emphasizes similar vowel sounds in words that are close together.

The answer is enjambment. A line of poetry is enjambed when it continues on to the subsequent line without punctuation. You can find enjambment in virtually all forms of poetry, and it serves many purposes. For instance, splitting a sentence between two lines without any punctuation gives special emphasis to the last word of the first line, a common poetical strategy.
The answer is not free verse, because that is a type of poetry which does not abide by a rhyme scheme, meter, or prescribed structural form.
The answer is not alliteration, because that is putting words together that begin with the same letter, such as: "She sells seashells by the seashore."
The answer is not assonance, because that is a type of rhyme in which neighboring words have the same (or similar) vowel sounds, creating a kind of internal rhyme, such as: "Hear the mellow wedding bells."
