Sprog is a British aspersion
for a child, akin to the American term "runt
", "ankle biter
" or "rug rat
". Sprog in all likelihood comes from the term "sprag
" which refers to a young salmon
. In the 18th century, sprag came to refer to a gay
, cheery youth.
By World War II
, "sprog" had entered into the British army's slang lexicon
and was used in a derogatory
sense to refer to a new recruit or someone in the lower ranks. After the war, former soldiers started making lots and lots and lots of babies and sprog, being too good a word to forget, got applied to children.
