Definition of Paralysis
Paralysis is defined as the loss of the ability to move (motor function) and sometimes to feel (sensory function) in a part of the body. It can be temporary or permanent, partial or complete, and it can affect any part of the body. Paralysis is not a disease in itself, but rather a symptom of an underlying condition.
In grammatical terms, “paralysis” is a singular noun. It belongs to the class of nouns that originate from Greek and Latin and follow specific rules for pluralization. Understanding its origin helps clarify why its plural form is “paralyses” rather than simply adding an “-s” to the end. This singular form is used when referring to a single instance or type of paralysis.
The term “paralysis” can be used in various contexts, including medical, scientific, and even metaphorical situations. In medicine, it is used to describe the specific loss of function in a particular area of the body. In a metaphorical sense, it can describe a state of inaction or inability to proceed, such as “analysis paralysis,” where overthinking leads to an inability to make a decision.
Structural Breakdown
The word “paralysis” comes from the Greek word paralyein, meaning “to disable on one side.” The suffix “-sis” in “paralysis” indicates a condition or process. Many words ending in “-sis” in the singular form change to “-ses” in the plural form when derived from Greek. This pattern is consistent with other similar words in the English language.
The plural form, “paralyses,” follows this established pattern. The “-sis” ending is replaced with “-ses” to indicate multiple instances or types of paralysis. This transformation is a standard rule for nouns of Greek origin ending in “-sis.” This grammatical structure is important to remember to ensure correct usage in writing and speaking.
Therefore, the structural breakdown of “paralysis” and “paralyses” is as follows:
- Singular: paralysis (condition or process of being disabled)
- Plural: paralyses (multiple instances or types of paralysis)
Understanding this structure is vital for accurate and effective communication, especially in technical or medical contexts.
Types of Paralysis
Paralysis can be classified in several ways, depending on the extent and location of the loss of function. Here are some of the main types:
Localized vs. Generalized Paralysis
Localized paralysis affects a specific area of the body, such as a hand, foot, or facial muscle. Generalized paralysis affects a larger portion of the body.
Monoplegia
Monoplegia is paralysis of one limb, such as an arm or a leg. It is often caused by brain injuries or spinal cord damage that affects a specific nerve pathway.
Hemiplegia
Hemiplegia is paralysis of one side of the body (left or right). This type of paralysis is commonly caused by stroke, which affects the brain’s ability to control movement on one side of the body.
Paraplegia
Paraplegia is paralysis of the lower body, including both legs and sometimes the pelvic organs. It is usually caused by spinal cord injuries in the thoracic or lumbar regions.
Quadriplegia (or Tetraplegia)
Quadriplegia, also known as tetraplegia, is paralysis of all four limbs (both arms and legs). This is typically caused by spinal cord injuries in the cervical region of the spine.
Spastic vs. Flaccid Paralysis
Spastic paralysis involves muscle stiffness and spasms, making movement difficult. Flaccid paralysis involves muscle weakness and loss of muscle tone.

- Singular Usage: Use “paralysis” when referring to a general condition or a specific instance of paralysis. For example, “He suffered paralysis after the accident.”

Advanced Topics: Irregular Plurals and Latin Derivatives
The English language contains numerous irregular plurals and words derived from Latin and Greek, each with its own set of rules and exceptions. The pluralization of “paralysis” to “paralyses” is just one example of how understanding the etymology of a word can help determine its correct plural form.
Other examples of nouns ending in “-sis” that follow the same pluralization rule include:
- Analysis: analyses
- Crisis: crises
- Hypothesis: hypotheses
- Thesis: theses
However, it’s important to note that not all words ending in “-sis” follow this rule. Some words have been Anglicized over time and now commonly use the regular “-s” plural. For example, “emphasis” can be pluralized as either “emphases” or “emphasises,” with “emphases” being more common in American English.
Understanding these nuances requires a deeper understanding of linguistic history and the evolution of the English language. Advanced learners should familiarize themselves with common Latin and Greek roots and suffixes to better predict the plural forms of unfamiliar words.
