Review of Prefixes, Stems, and Suffixes

1. Analyze each of the following words into their prefixes, stems and suffixes as indicated in the formulas given in the middle column. ‘Pr’ equals ‘Prefix’, ‘St’ equals ‘Stem’, and ‘Su’ equals ‘Suffix’. Remember that some stems consist of just a base. Be sure to show all cases of final <e> deletion, twinning, changing of <y> to <\mathrm{i}> and assimilation:

Word Formula = Analysis
misaddressed Pr^1 + Pr^2 + St + Su = mis + ad + dress + ed
assuring Pr + St + Su = a\cancel{d} + s + sur\cancel{e} + ing
misinforms Pr^1 + Pr^2 + St + Su = mis + in + form + s
submariner Pr + St + Su = sub + marin\cancel{e} + er
successfully Pr + St + Su^1 + Su^2 = su\cancel{b} + c + cess + ful + ly
observers Pr + St + Su^1 + Su^2 = ob + serv\cancel{e} + er + s
illustrating Pr + St = i\cancel{n} + l + lustrating
unimpressed Pr^1 + Pr^2 + St + Su = un + i\cancel{n} + m + press + ed
reoccurring Pr^1 + Pr^2 + St + Su = re + o\cancel{b} + c + cur + r + ing
adventurers Pr + St + Su^1 + Su^2 = ad + venture + er + s
disappearing Pr^1 + Pr^2 + St + Su = dis + a\cancel{d} + p + pear + ing
inquirers Pr + St + Su^1 + Su^2 = in + quir\cancel{e} + er + s
suppliers Pr + St + Su^1 + Su^2 = su\cancel{b} + p + pl\cancel{y} + i + er + s
unaccompanied Pr^1 + Pr^2 + St + Su = un + a\cancel{d} + c + compan\cancel{y} + i + ed
uninvolved Pr^1 + Pr^2 + St + Su = un + in + volv\cancel{e} + ed
misassigned Pr^1 + Pr^2 + St + Su = mis + a\cancel{d} + s + sign + ed
subscribers Pr + St + Su^1 + Su^2 = sub + scrib\cancel{e} + er + s
disadvantaged Pr^1 + Pr^2 + St + Su = dis + ad + vantag\cancel{e} + ed
unassisted Pr^1 + Pr^2 + St + Su = un + a\cancel{d} + s + sist + ed
sufferers Pr + St + Su^1 + Su^2 = su\cancel{b} + f + fer + er + s
unaffected Pr^1 + Pr^2 + St + Su = un + a\cancel{d} + f + fect + ed
substituting Pr + St + Su = sub + stitut\cancel{e} + ing
straightened St + Su^1 + Su^2 = straight + en + ed
occupies Pr + St + Su = o\cancel{b} + c + cup\cancel{y} + i + es

2. Combine the following prefixes, stems, and suffixes. Again, be sure to show all changes that occur when the elements combine:

Prefixes, Stems, and Suffixes = Word
un + a\cancel{d} + p + prov\cancel{e} + ed = unapproved
dis + a\cancel{d} + p + point + ment + s = disappointments
in + form + er + s = informers
ad + just + er + s = adjusters
a\cancel{d} + c + cid + ent + al + ly = accidentally
re + o\cancel{b} + cur + r + ing = reoccurring
o\cancel{b} + p + portun\cancel{e} + ist + s = opportunists
su\cancel{b} + g + gest + ion + s = suggestions
sub + tract + ion = subtraction
o\cancel{b} + p + posit\cancel{e} + ion = opposition
in + de + pend + ent + ly = independently
i\cancel{n} + l + lustr + at\cancel{e} + ion + s = illustrations
a\cancel{d} + s + sort + ment = assortment
a\cancel{d} + s + sign + ment = assignment
i\cancel{n} + l + lus + ion + s = illusions
in + vent + or + s = inventors
ad + opt + ion = adoption
