Agglutinative languages break standard tokenization by packing information into single words

URL: https://portkey.ai/blog/prompt-engineering-for-low-resource-languages/

Extract

Languages like Tamil and Bengali "follow completely different rules regarding tokenization and morphological complexity." Agglutinative languages "pack complex information into single words" with "incompatible writing systems." Code-mixing (e.g., Hinglish) creates further confusion about grammatical rules. Chain-of-Translation prompting (translating to English, processing, translating back) reduced errors by 2.32-5.29% across models.

Relevance to Hypotheses

Hypothesis Relationship Strength
H1 Supports Agglutinative structure creates specific tokenization challenges
H2 Contradicts Morphological complexity directly affects prompt processing
H3 Supports The challenge manifests through tokenization, and a translation-based workaround exists

Context

The Chain-of-Translation technique (translate to English, process, translate back) is a practical workaround that acknowledges the structural challenge while routing around it through English — supporting the view that the challenge is mediated through computational mechanisms.
