Explanation:

The suffix -ive contributes to the meaning of the words in that it indicates that someone possesses a particular characteristic/acts in a particular way described in the verb itself.

Explanation:

The meaning of the suffix -ive is 'having the nature of.' We add this suffix to verbs, in order to form adjectives: (to) act + ive = active. This suffix tells us that someone possesses a particular characteristic described in the verb itself. In case of 'active', the suffix indicates that someone is always ready for action. Similarly, the suffix -ive in 'inclusive' indicates that someone has the nature of including other people. When it comes to 'possessive', the suffix tells us that someone likes to 'possess' other people.
