Word Story 13:

Toe The Line

Meaning: To conform to an established standard or political program.
Origin
There is some confusion between 'toe the line' and the frequently seen misspelling 'tow the line'. The 'tow' version is no doubt encouraged by the fact that ropes or cables on ships are often called lines and that 'tow lines' are commonplace nautical items.
The earlier meaning of 'to toe the line' was to position one's toes next to a marked line in order to be ready to start a race, or some other undertaking. The earliest version we know about is from The Diverting History of John Bull and Brother Jonathan, 1813, by 'Hector Bull-Us' - known to his family and friends as James Paulding:
"He began to think it was high time to toe the mark."
Pauling was using the figurative rather than literal meaning of the phrase, i.e. to 'toe the mark' was to conform to a set standard.
Going back to the original, literal 'toeing' of a line; there are many circumstances where one might place one's toes up to a line - the start of a sporting event, standing in formation on parade, etc, etc. So, which is the source of the phrase?
One explanation that is often repeated is that the phrase derives from the British House of Commons. Arguments in the House are often heated. To deter members of opposing parties from attacking each other, two parallel red lines are marked, two sword-lengths apart, on the floor of the house. MPs are expected to stay behind these lines when a speech is in progress. Members, of course, no longer carry swords, but the tradition remains. Visitors to the House of Commons are very likely to hear this tale related by a tour guide. The parliamentary link may be strengthened in some people's minds because of the 'toe the party line' usage, which relates to orthodoxy in politics.
Other early examples of 'toe the ...' have a nautical connection. In the 19th century, sailors were expected to prepare themselves for group punishment by standing in formation on deck and 'toeing the line' between boards - also called 'toeing the crack'. Which is the source? Well, no one knows. What is for certain - it is toe, not tow.
 In Context: If you decide not to toe the line, you might get your toes stepped upon!
