Final answer:
The word 'contaminate' suggests impurity, hence 'immaculate' suggests purity and cleanliness, as 'im-' means 'not'. This is an example of using prefixes to understand word meanings.
Step-by-step explanation:
The word contaminate implies the presence of impurities or pollution. Knowing this, we can deduce that immaculate would relate to the absence of these impurities, as 'im-' is a prefix meaning 'not' in Latin. Therefore, immaculate suggests something that is completely clean or without blemish - the opposite of contaminated.
The process of understanding meanings of unknown words by knowing the meaning of their components is known as morphological analysis. It's a valuable tool for vocabulary development.
