Sentence length plays a fundamental role in determining readability, fluency, and translation quality in both human and machine contexts. It directly affects how information is processed, understood, and reproduced across languages. Short sentences are valued for their clarity and simplicity, allowing readers and translation systems to handle information efficiently. However, excessive brevity can cause fragmented meaning and reduced cohesion. In contrast, long sentences enhance syntactic richness and express complex ideas but often challenge comprehension and computational processing. In Neural Machine Translation (NMT), sentence length has a measurable impact on performance and accuracy. Short inputs may lead to context loss, while overly long sentences increase computational complexity and risk hallucination errors. Modern Transformer-based models such as BERT and mBART process text through fixed attention windows, making sentence length optimization crucial for translation reliability. From a human perspective, variation in sentence length improves rhythm, engagement, and rhetorical balance. Studies in education, linguistics, and professional communication reveal that a mixture of short and long sentences enhances both understanding and stylistic quality. This review synthesizes findings across disciplines to demonstrate that no universal ideal sentence length exists; rather, effective translation and writing rely on balance and adaptability. The insights presented here are essential for educators, linguists, and AI researchers developing systems that promote clarity, coherence, and translation quality across diverse languages and domains.
