1. Normally after stressed long vowels and consonants, [j] is spelled <g> and after stressed short vowels it is spelled <dg>. Usually after an unstressed vowel [j] is spelled <g>. And very often it is in the suffix -age, which forms nouns, usually (but not always) from verbs:
pack + age = package
Verb + age = Noun
Combine the following stems and suffixes to form nouns. Show any changes:
carry + i
2. Try some the other way around. Notice that not all the stems in this group are verbs:
= carry+ i
= lug + g
= bag + g
3. The suffix -age is often added to bound stems. Add -age to each of the following bound stems to form a noun:
Noun: Bound Stem +age
Notice that in the suffix -age the letter <a> spells an unstressed short <i>.
Item 1. The one stem in the table that is not a verb is percent, though all of them also have noun meanings as well as verb meanings. Most monosyllabic English verbs can also function as nouns.
Item 3. There is no twinning in words like damage and savage because the twinning rule only applies to free stems, and dam and sav are not free stems; they are bound. The bound base dam is not related to either of the free bases dam. The first dam refers to a barrier to hold back water and is not related to the second, which refers to the mother of four-footed animals. Actually, the bound base dam is more closely related to the mild oath damn, since both descend from the Latin damnum “damage, loss, hurt.” The bound base sav has the root meaning “of the woods, wild” and is related to our word sylvan.
