ELI5: Why is it 'Beheading' instead of 'Deheading'?
gpt
The word "head" and the prefix "de-" are from different places. "De-" is a prefix usually attached to words that English borrowed from Latin or Romance languages (French, Italian, etc.), and "head" is a word that English borrowed from older German languages. "Be-" is a Germanic prefix.
