Plural Form of Thesis – A Complete Guide by Anushram
The English language often confuses learners when it comes to irregular plural forms, and one classic example is the plural form of thesis. While most nouns form their plural simply by adding “-s” or “-es,” certain words derived from Latin or Greek follow different rules. The word thesis is one such term. Understanding the plural form of thesis is important for students, researchers, writers, and academic professionals.
At Anushram, we specialize in academic writing support, research guidance, and thesis services, so we frequently deal with multiple theses. In this comprehensive guide, we will explore the meaning, correct pluralization, grammar rules, usage examples, and common mistakes related to the plural form of thesis.
What is a Thesis?
Before we explore the plural form of thesis, let’s understand what a thesis actually means. A thesis is an academic document presenting an author’s research and findings, typically submitted for higher education degrees such as a Master’s or Ph.D. It serves as evidence of a student’s research capabilities, analytical thinking, and subject expertise.
A thesis is more than just a paper; it’s a structured argument supported by evidence. When there is more than one thesis, we use its plural form, which is theses.
Plural Form of Thesis – The Correct Answer
The plural form of thesis is theses.
- Singular: Thesis
- Plural: Theses
This irregular plural form comes from Greek, where “-is” endings change to “-es” in the plural. The same rule applies to other words like crisis → crises and analysis → analyses.
Why is it Theses and Not Thesises?
In English, some words do not follow the regular pluralization rules. Since thesis has its roots in Greek, its plural form of thesis changes “-is” to “-es” rather than adding “-s.”
Example:
- Incorrect: I have written three thesises.
- Correct: I have written three theses.
At Anushram, we always ensure that your academic content follows correct grammar rules, including the proper use of the plural form of thesis.
