present tense root: nîşanî -d-
I am showing him. = Ez nîşanî wî didim.
Note: when used in a sentence to say that we showed something to someone, several things happen:
1. nîşan takes an î on the end of the word
2. the name of the person or the pronoun comes between nîşanî and dan,
3. the root of dan becomes -d-, and
4. the present tense marker di- comes at the beginning of -d-.
