“Alliterate or die!” That was a poster a former colleague saw pasted to a newsroom wall while doing a shift at infamous British tabloid The Sun. Alliteration’s power to make words stick owes itself to the repetition of sounds. It’s something a lot of retailers know, hence “Wine Wednesdays,” “Free Cleaning Friday” or “Saturday Style.” Indeed, once you get started, it’s pretty hard to stop: Too Good to be True Tuesdays, Wet and Wild Wednesdays, Fried Food Fridays (for the staff, of course).
