verb (toes, toeing, toed)
Old English tā, of Germanic origin; related to Dutch tee and German Zeh, Zehe. Current senses of the verb date from the mid 19th century
The phrase toe the line, derived from an earlier sense ‘stand with one’s toes touching a line, as for a contest’, is sometimes misunderstood and written as tow the line. In the Oxford English Corpus around 15 per cent of the citations for the phrase are for the erroneous form.
Keep the e in toeing; it does not follow the usual rule that a final silent e is dropped when adding endings that begin with a vowel.
Do not confuse toe with tow. The correct phrase is toe the line, which originally meant 'stand with the tips of the toes exactly touching a line' (for instance, at the start of a race).
