Answer:
Group I. If the root is a full word, the ending is usually -able.
Group II. When the root is a full word except for a final e, the forms usually are spelled with -able and drop the finale.
Group III. The suffix -able always follows the letter i. Thus, if you follow our English custom of changing y to i in these words, you will add -able.
Group IV. When the root has other forms built on the letter a, the -able form is used.
Group V. When the root ends in hard c orhard g, -able is used. The suffix -able is the only possible ending after hard c or g, in order to keep the proper pronunciation.
Group VI. When the root is not a full word, -ible is used.
Group VII. When the word has an immediate -tion form, -ible is used.
Group VIII. When the root ends in ns, miss, or soft c or g, -ible is used.
The central idea of Mike kubick's article 'The salem (and other) witch hunts' was to show how people, mainly women, were chased by the Church and obliged to confess crimes they hadn't committed. All this hunt was made 'in the name of God' and it was very difficult to escape or to think about denouncing the problem to authorities since they were the same people that committed such an abominable act.
