Write a paragraph with some of these words: abate, admonish, addict, adjacent, acquire, accelerate, acrid, agitate, affliction, adobe, aspire, abnormal, acknowledge, acclaim, and abrupt.

By the time people realize they are an addict to something or someone, they will do whatever in their power to stop this addiction.  Even though they might acquire to return to their addiction, they aspire to not be addicted to anything anymore.  The first step that the addicts would take is to acknowledge their addiction.  This can be seen by the affliction it has on people.  These people might be a bit agitated and have an adjacent attitude, but it is only temporary, as they are going without something they previously saw as necessary.  The more support addicts have, the more they can accelerate their healing.  

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
