Question

Fill in the blank with the most appropriate word.
He has good _____ over the world-famous languages.
a) authority
b) expertise
c) hold
d) Command
e) Knowledge

Answer 1

Hint: When we talk about knowing a language very well, we talk about a person’s knowledge of the language. The expression to be used is a well-known phrase used in the regular English language. Note the preposition used- “over”. Choose an option accordingly.

Complete answer:
 The correct answer is option d. Having a command over a language is a common usage of the phrase. When we have to say that someone knows a language well, we say that he or she has a good command over the language.
Option a is wrong because “authority” is not used in cases of languages. It is used with situations which include law, politics, etc.
Option b is wrong because with the word “expertise” we use the preposition “in” and not “over”. He has expertise in cooking.
Option c is wrong because “hold” is used for situations and not languages. The director had a good hold over the meeting. This means that he was conducting the meeting well.
Option e is wrong because “knowledge” is used with the prepositions “in” or “of”. He has a rich knowledge of literature. His knowledge is rich in history.

Note:
 Always take note of the preposition used in the sentence. If more than one word goes with that preposition, then try to use the word in sentences of your own and see which is a better suit. Remember that the instructions of the questions talk about finding the appropriate word so we have to choose the word which is not only correct but also the best fit.
