Step 1: Understanding the Question:
The question asks us to identify the word that has been spelled incorrectly among the given four options.
This assesses the candidate's familiarity with academic suffixes and word structures.
Step 2: Key Concepts and Grammar Rules:
Suffixes such as ``-ary'' and ``-ery'' can be confusing.
The suffix ``-ary'' is used to form adjectives meaning ``relating to'' or ``connected with'', whereas ``-ery'' usually denotes a business, place, or collective state.
Step 3: Detailed Explanation:
• Option (A) - assassination: This spelling is correct.
A helpful memory aid for this word is to note that it contains the word ``ass'' twice, followed by ``i'' and ``nation'' (ass-ass-i-nation).
• Option (B) - multidisciplinery: This spelling is incorrect.
The word is derived from the root ``discipline'' combined with the prefix ``multi-'' and the suffix ``-ary''.
Therefore, the correct spelling is ``multidisciplinary'' ending with an 'a' instead of an 'e'.
• Option (C) - linguistic: This spelling is correct.
It relates to language or linguistics, derived from the Latin word ``lingua'' meaning tongue.
• Option (D) - refurbished: This spelling is correct.
It is the past participle form of the verb ``refurbish'', meaning to renovate or redecorate.
Step 4: Final Answer:
Since option (B) is spelled incorrectly, it is the designated answer.
