Answer in explanation
Step-by-step explanation:
Since it's asking you to make nouns out of the words, they (the words) need to be changed to name (either a specific or class of) a person, place, or thing.
Quote:
"noun: identify any of a class of people, places, or things (common noun), or name a particular one of these (proper noun)"
3.6:
1- realist (a person who sees things as they are
2- musician (someone who plays a musical instrument)
3- nationalist (a person who strongly identifies with their own nation)
4- membership (being a member of a group)
5- medalist (someone given a medal)
6- drama ( a play for theater, radio, or television )
7- psychiatrist/psychiatry ( the diagnosis and treatment of mental illness) **
8- race (a competition to see who is faster )
9- companionship (feeling of friendship)
10- activist (person who campaigns to bring about political or social change)
11- wisdom (someone who is wise)
12- receptionist (working at the front desk)
13- knighthood
14- diarist/diary ( person who writes a diary- a daily record book)
15- friendship/friend (the state of being friends)
(if possible, a dictionary written in English or an online dictionary can help you with definitions/words you don't understand.
Some words are still a noun when changed, so a dictionary is helpful with that!)
Hope this helps!
