Verbal Roots Under separate headings we have already dealt with changes in the basic concept of the verb root by adding certain suffixes: -in for reflexive, -iş for reciprocal action, -il for passive, -dir for causative and -me for negative. These suffixes were added to verb roots.
Here we are going to deal with verbal roots obtained by adding certain suffixes to substantives, adjectives, pronouns and adverbs. It is not easy to give the sense-relation between a word and the verb roots derived from them. It is not as simple as giving a general definition of the function of the suffixes. The resulting verb could be any action that bears a relation to the word it derives from.
