Sentence Break - Lower
Lower is a specific classification used to define how text behaves at sentence boundaries, indicating that a character belongs to the lowercase letter category for the purpose of line and sentence segmentation. It means that these characters, such as ‘a’, ‘b’, or ‘z’, are treated as normal content within a sentence, neither initiating a break nor preventing one unless adjacent to punctuation or other break-inducing characters. In practice, the lower value ensures that lowercase letters do not trigger a sentence end by themselves, but they can be part of the final word before a period, question mark, or exclamation point, thereby allowing the algorithm to correctly identify the actual sentence terminus based on surrounding context, rather than on the letter itself.
