Hint: A word is a single distinct meaningful element of speech or writing, used with others (or sometimes alone) to form a sentence and typically shown with space on either side when written or printed.
Complete answer: In the given question, we have to find out the correct spelling of the word ‘twelfth'. There are some rules of how to check spelling, such as – If two vowels are next to each other in a word, the second vowel is silent. For example, in the word coat, you only hear the “O” pronounced. Here, the word has only one vowel. Now, let us examine all the given options to find out the correct answer : Option ‘a’ is Twelveth. It is the incorrect spelling of ‘twelfth’ as we cannot use ‘ve’ after ‘l’. There is no need of an ‘e’ at that place. Option ‘b’ is Twelvth. It is also an incorrect spelling as there is no need of a ‘v’ here. The sound of a ‘f’ is needed after ‘l’. So, we will eliminate this option Option ‘c' is Twelfth. It is the correct spelling of twelfth as there is a ‘f’ at the correct place and the vowel is also correctly placed. Option ‘d’ is None of the above. This option has to be chosen if all the other three options are incorrect or not suitable for the given option. Hence, option ‘c’ is the correct option.
Note: Despite all of the tricks and tips for checking word spellings, some people are simply poor spellers. In these cases, learning how to look words up in the dictionary and relying on spell check can be useful. Carefully proofreading and editing written works can help those lacking spelling skills.
