Which one of the following words illustrates the addition of a vowel suffiix

a. tenderness
b. likelihood
c. careful
d. dangerously

The answer on this item is not found in the choices. Why? Simply because vowel suffix is only added when the root word or the word has a silent e which has to be dropped. Here is the analysis: tenderness- root word: tender, -ness is added as a suffix, obviously it is a consonant suffix Likelihood- root word: likely, -hood was added (“y” from the word likely is changed to “i”) Careful- root word: care, -ful is added as a suffix. Although the word has a silent “e”, the silent “e” was not dropped but kept since you cannot spell “careful” as “carful”. Thus, this is consonant suffix. Consonant suffix are added to words with silent “e” but this silent "e” is not dropped but kept. Dangerously- root word: danger- -ous is added as suffix, another word to consider is dangerous, -ly was added as suffix which is definitely a consonant suffix. >>>Vowel suffix are added to words with silent “e”, before adding the suffix, “e” should be dropped. For instance: Bake- drop “e’ and add -ed Take- drop “e” and add -en Ride- drop “e” and add -ing. Hope this helps.:)
