Order of Language Inclusion in Sequential Fine-Tuning for Cross-Lingual Euphemism Detection in Yoruba

Euphemisms are culturally variable and often ambiguous, posing challenges for language models, especially in low-resource settings. This paper investigates how cross-lingual transfer via sequential fine-tuning affects euphemism detection across five languages: English, Spanish, Chinese, Turkish, and Yoruba. We compare sequential fine-tuning with monolingual and simultaneous fine-tuning using XLM-R and mBERT, analyzing how performance is shaped by language pairings, typological features, and pretraining coverage. Results show that sequential fine-tuning with a high-resource L1 improves L2 perfo Research goal: How does the order of language inclusion in sequential fine-tuning affect downstream cross-lingual euphemism detection performance on Yoruba, as measured by accuracy on XTREME-R and F1 score on SEED-Bench when comparing different ordering heuristics (e.g., typological distance, resource availability)?
