Final answer:
Etymology is accurately described as the study of word origins, which is directly relevant to the field of anatomy and physiology where terms are often derived from Greek and Latin roots.
Step-by-step explanation:
The statement that etymology is the study of word origins is indeed true. Etymology involves analyzing the history of words, understanding their origins, and how their form and meaning have changed over time.
When choosing the term closest in meaning to 'hypothesis', the most fitting word is suggestion (option d), as a hypothesis is a proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Words most likely to be borrowed from another language tend to be those referring to objects or concepts that were originally foreign to the borrowing culture, rather than words for family members (option A) or pronouns (option B), which are more integral to the core vocabulary of a language.
Etymology is particularly important in certain fields, such as anatomy and physiology, where understanding the Greek and Latin roots of terminology can greatly assist with learning the names, locations, and functions of muscles in the human body.
