Question

Select the plural of the foreign word given below:
Thesis
A. Thesises
B. Thesis’s
C. Theses
D. Thesa

Answer 1

Hint: Some plural words are exceptions to the rule and do not follow the addition of ‘s’ at the end of the word. They have their special endings.

Complete answer:
When the noun refers to one item, the singular number is used. The plural number is used when more than one object is referred to in the noun. A noun that is used for only one person or thing is said to be in the singular Number. Example: girl, child, pen, table, etc. A Noun that is used for more than one person or thing is said to be in the Plural Number. Example: Girls, men, pens, tables, etc.

There are many other ways of making a noun plural. The method of making a word plural depends on its endings. Words that have an ending ífe’ like life and knife changes into lives and knives. Words that end with ’ss’ like dress and loss change into dresses and losses.
Generally, when a word ends with 's' already, we do not add an 's' to the word to make it plural, nor do we add an apostrophe (the symbol ') as that is used to show possession, not plural.
This takes out options A) and B) and option d) is incorrect because such words do not exist.

The right option is option C) The word 'theses' is the specific plural for the singular form 'thesis’, making this an exceptional case.

Hence the correct answer is option ‘C’.

Note:Do not select any of the other options as the proper answer because they end with ‘s’. These words do not exist and are, therefore, incorrect.
