Did You Know?

Spilth is formed from the verb "spill" and the noun suffix -th. This suffix comes to us from Old English and is used to indicate an act or process (as in "spilth" or the more familiar "growth") or a state or condition (as in "breadth" or "length"). The earliest known use of "spilth" is in Shakespeare's Timon of Athens (c. 1607-08): "When our vaults have wept / With drunken spilth of wine…." In the senses of an act of spilling or of something spilled, English speakers today are much more likely to use the noun "spill" or sometimes "spillage," a word which, like "spilth," combines the verb "spill" with a suffix ("-age," this time borrowed from Old French) that can indicate an act or process.
