This study explored the types of question propositions between English and Yoruba, and their process in translation free from the former to the latter, and, vice versa, using the literal and idiomatic continuum of translation proposed by Larson (1984). The findings of the paper revealed that question translation between both languages has implications on the characteristics of language which affect translation. The similarities and peculiarities of each language as they affect the translation to Wh, Yes/no, Echo, Tag and Alternative questions in both languages were highlighted. Also underscored was the significance of translating question proposition between both languages in pedagogical and other contexts of communication.
