With the use of different suffixes (word endings, such as -er, -ian, -ist, -ness etc.) you can change what part of speech words are. Here are some examples:
VERB TO NOUN
- Play (verb) + er = Player (noun)
- Sing (verb) + er = Singer (noun)
- Act (verb) + or = Actor (noun)
- Music (verb) + ian = Musician (noun)
ADJECTIVE TO NOUN
- Happy (adjective) + ness = Happiness (noun)
- Crazy (adjective) + ness = Craziness (noun)
- Sad (adjective) + ness = Sadness (noun)
- Lazy (adjective) + ness = Laziness (noun)
