spitting image

Meanings

1. The exact likeness (of someone); a speaking or living image.

Etymology

An alteration of the earlier spitten image (see spitten). A popular folk etymology explains this phrase as deriving from the idea of a father spitting out a child whole from his mouth, as if giving birth. But spitten image actually developed from spit and image, where spit in this context means “likeness”. Terban further suggests a derivation of this sense of spit from the word spirit, but evidence for this is lacking. Another theory is that the idiom is Biblical, after an image of God spitting into dry earth to make the clay out of which Adam would be formed.
