Does Pragmatic Transfer Help Euphemism Detection? Evidence from Target-Span Marking

Abstract
Euphemism detection is often motivated as a pragmatic task: deciding whether a potentially euphemistic term (PET) is used euphemistically depends on context, communicative goals, politeness, topic sensitivity, and sentiment. A natural prediction is that auxiliary supervision from pragmatically related tasks should improve euphemism detection when target supervision is limited. We test this prediction for PET-style classification using XLM-R and mBERT in a feature-based transfer setting: auxiliary-tuned encoders are frozen and probed for euphemism detection. We compare sentence-level pragmatic proxy tasks with expression-level nonliteral tasks and with target inputs that either mark or omit the PET span. The results do not support a simple pragmatic-transfer account. Auxiliary transfer is unreliable, often reducing XLM-R performance and helping mBERT only inconsistently. The largest observed gains come from direct euphemism fine-tuning when the target PET is explicitly marked. The practical implication is to preserve target-span information and report source–target compatibility in transfer experiments.
