|informal spit, Also called: spit and image a person who bears a strong physical resemblance to another, esp to a relative|
|[C19: modification of spit and image, from |
|a stew of meat, vegetables, potatoes, etc.|
|a scrap or morsel of food left at a meal.|
A precise resemblance, especially in closely related persons. For example, Dirk is the spitting image of his grandfather. This idiom alludes to the earlier use of the noun spit for "likeness," in turn probably derived from an old proverb, "as like as one as if he had been spit out of his mouth" (c. 1400). The current idiom dates from about 1900.
