Ped- conveys multiple meanings, from different Latin and Ancient Greek root words:

In meanings 2, 3, and 4, the spelling remains ped- in Commonwealth English words that begin with these letters. Not all derived words do; e.g., petard (a small bomb) is from meaning 4, and entered English from Middle French {{lang|frm|pétard}} for the same thing (originally literally meaning 'fart', it remains an uncommon Modern French word for 'firecracker').
