The Suffix -ive

1. The suffix -ive changes nouns and verbs into adjectives. It adds the meaning “tending to” or “doing” or “being.” Each of the following words consists of a verb or noun plus the suffix -ive. Analyze each one. Be sure to show any cases where a silent final <e> was deleted:

Adjective = Noun or verb + Suffix
defensive = defens$\cancel{e}$ + ive
massive = +
excessive = +
supportive = +
reflective = +
effective = +
directive = +
exhaustive = +
detective = +
narrative = +
disruptive = +
subjective = +
active = +
attractive = +
retrospective = +

2. Here are some the other way around. Combine the elements to make adjectives. Show any changes that occur when the elements combine:

ex + cess + ive =
intro + spect + ive =
ob + struct + ive =
retro + spect + ive =
ob + ject + ive =
ad + gress + ive =
sub + ject + ive =
re + strict + ive =
re + cept + ive =
per + cept + ive =
de + fect + ive =
ex + secute + ive =
dis + rupt + ive =

3. Some adjectives are formed not by adding -ive to nouns or verbs, but rather to bound stems. Each of the bound stems is related to a verb that is spelled slightly differently from the bound stem. (Usually verb has a <d> where the bound stem has an $<\text{s}>$.) Combine the following bound stems and suffixes to make adjectives, and then in the right hand column write the related verb:

Bound stem + suffix = Adjective Related Verb
extens + ive = extensive extend
attent + ive =
inclus + ive =
exclus + ive =
explos + ive =

4. Often an adjective that ends in -ive comes to be used also as a noun. For instance, the verb execute becomes the adjective executive, which is then used as a noun, as in “She is an executive in a computer company.” In the tables in this lesson there are at least six adjectives that end in -ive and can also be used as nouns. See how many you can find:
