Etymology
the word 'sidewall' is a transparent english compound, formed by directly combining two old english nouns. 'side', with its germanic roots, originally referred to the flank of a body, evolving to denote any lateral position. 'wall', derived from the latin vallum meaning a rampart or palisade, broadened in meaning to signify any continuous vertical structure serving as a boundary or support. their union in the late 18th century logically created a term for the lateral structural surface of an object, first applied to the flanks of ships and later to the vertical portion of a pneumatic tire.
