Here's why:

* Historical Foundation: Latin was the language of science and scholarship during the Renaissance and Enlightenment, making it the standard for naming new species.

* Universality: Latin is a dead language, meaning it doesn't evolve or change. This ensures that scientific names remain stable and universally understood by scientists worldwide, regardless of their native languages.

* Formal Structure: Latin grammar provides a structured framework for constructing scientific names, ensuring consistency and clarity.

* Tradition: Despite the adoption of English as the primary language of science today, the tradition of using Latin for scientific names remains strong.

While Latin is the basis, scientific names often incorporate elements from other languages, including Greek, but the core structure and grammar adhere to Latin conventions.
