For want of a nail

"For want of a nail" is a proverb, having numerous variations over several centuries, reminding that seemingly unimportant acts or omissions can have grave and unforeseen consequences through a domino effect.

Poet George Herbert recorded it in 1640 as "For want of a naile the shoe is lost, for want of a shoe the horse is lost, for want of a horse the rider is lost."^[1] A longer version noted by Benjamin Franklin in 1758 runs:

For want of a nail the shoe was lost;
for want of a shoe the horse was lost;
and for want of a horse the rider was lost,
being overtaken and slain by the enemy,
all for want of care about a horse-shoe nail.^[2][3]

History

The proverb is found in a number of forms. The poet George Herbert included it in a 1640 collection of aphorisms, and Benjamin Franklin included a version in his 1758 Poor Richard's Almanack.^[4][5][6]

Predecessors include the following:

• Middle High German (positively formulated): Diz ſagent uns die wîſen, ein nagel behalt ein îſen, ein îſen ein ros, ein ros ein man, ein man ein burc, der ſtrîten kan. ("The wise tell us that a nail keeps a shoe, a shoe a horse, a horse a man, a man a castle, that can fight.")^[7]
• For sparinge of a litel cost, Fulofte time a man hath lost, The large cote for the hod. ("For sparing a little cost often a man has lost the large coat for the hood.")^{[8][whose translation?][9]}
• Middle French: Par ung seul clou perd on ung bon cheval. (Modern French: Par seulement un clou, on perd un bon cheval.; English: "By just one nail one loses a good horse.") (c 1507 Jean Molinet, Faictz Dictz D., v768).^[9][10]
• "The French-men haue a military prouerbe; 'The losse of a nayle, the losse of an army'. The want of a nayle looseth the shooe, the losse of shooe troubles the horse, the horse indangereth the rider, the rider breaking his ranke molests the company, so farre as to hazard the whole Army". (1629 Thomas Adams (clergyman), "The Works of Thomas Adams: The Sum of His Sermons, Meditations, And Other Divine And Moral Discourses", p. 714")^[9][11]
