bofa (English)

Where does "bofa" come from?

The English interjection 'bofa' originated as a contraction of the words 'both' and 'of'[1]. The latter component, 'of', traces its deep history back to the Proto-Indo-European '*h₂epó', meaning 'away', and evolved through Proto-Germanic and Old English stages[2][4][5][7]. Meanwhile, the word 'both' descends from Middle English 'bothe', which was influenced by Old English terms for 'both the' and reinforced by Old Norse forms like 'báðir', ultimately reaching back to a Proto-Germanic origin in '*bai'[3][6][10].

Open questions

• The precise Proto-Indo-European reconstruction for the root of both is debated, with various scholars linking it to *h₂m̥bʰi while others suggest only the first element is related. [12]
