Answer

To solve the question regarding which statement is not true for the binomial system of nomenclature, we will analyze each option provided:

1. **Biological names are generally in Latin or Latinized or derived from Latin irrespective of their origin.**
- This statement is true. The binomial nomenclature system uses Latin or Latinized terms for naming organisms, regardless of their original language.

2. **The first word in a biological name represents the species while the second word denotes the genus.**
- This statement is not true. In the binomial system, the first word represents the genus, while the second word represents the species. Therefore, this statement is incorrect.

3. **The first word of biological name starts with a capital letter and the first letter of the second word starts with a small letter.**
- This statement is true. In binomial nomenclature, the genus name (first word) is capitalized, and the species name (second word) starts with a lowercase letter.

4. **Name of the author is written in abbreviated form after the specific epithet.**
- This statement is also true. The author’s name is typically abbreviated and placed after the species name.

Based on the analysis, the statement that is not true for the binomial system of nomenclature is:

**The first word in a biological name represents the species while the second word denotes the genus.**
