Answer:
The correct anser is: true.
Step-by-step explanation:
Morphology is a core part of linguistic and it refers to the study of the words' internal structure, undestanding words as the smallest independent units of language.
Words exhibit the following characteristics: (1) they do not depend on other words, (2) they can be separated from other units or words and (3) they can change position. Therefore, since words are independent, can be separated from other words, and move around in sentences, it could be said that morphology is arbitrary rather than systematic.
