Question

divide dissatisfaction into morpheme

Answer 1

When we teach a child to speak longer words, we break it into small parts so that it can first pronounce each part and then combine all to speak the long word.
Similarly, when a word is divided into smaller meaningful units/parts its called morpheme.
1.  Dethrone = De > Throne
2. Irregularities = Ir > Regularity > es
3. Innings = Inning > s
4. Revitalize = Re > Vital > ize
5. Lovelier = Love > ly > er
6. Disallow = Dis < Allow
7. Voter = Vote < er
8. Destabilize = De > stable > ize
9. Insanity - In > Sane > ity
10. Unlikely = Un > like > ly

Sorry bud but I have this information that might help you to divide your word.
