The question asks us to identify the correctly spelled word from the given options. Let's evaluate each word:
- consanguineous: This word is correctly spelled. It means "related by blood" or "descended from the same ancestor." The prefix "con-" means "together" or "with" and "sanguine" relates to "blood."
- consenguineous: This spelling is incorrect because it erroneously includes an extra 'e,' making it awkward and not aligning with the correct pronunciation or etymology of the word.
- consanguinous: This spelling is also incorrect as it omits the 'e' before 'ous,' which is necessary to form the correct ending for an adjective meaning "of or pertaining to blood relations."
- consanguneous: This option is misspelled because it incorrectly positions 'u' before 'n.' The correct sequence should be "sangui" followed by "neous."
Based on the evaluation, the correct answer is consanguineous.
In conclusion, understanding the root and etymology of words can aid in identifying correct spelling, especially with complex terms originating from Latin or Greek.
