In falconry, a cadge is a frame on which hawks are carried. In shape, it’s traditionally a square, padded wooden frame on which the hooded hawks perch; it’s hung from a man’s shoulders by straps. Nobody is entirely sure where its name comes from, but the experts believe it was an alteration of cage under the influence of the old verb to cadge, meaning to carry things.
If you trace that verb back, it starts its recorded life about 1600 in reference to men named cadgers in Northern England and Scotland, a noun which is known slightly earlier, from the late fifteenth century. They were itinerant hawkers and peddlers with a horse and cart or a packhorse, who collected butter, eggs, poultry and other farm produce for sale in the local market and who in return took out small items to farms from the local shops. They did not enjoy a high reputation: often hard bargainers and hard swearers (“to curse like a cadger” was once a Scots simile), they were at the bottom of the social order. An old Scots proverb says “the king’s errand may come to the cadger’s gate yet”, meaning that even the highest in the land may sometimes need the help of the most humble.
In the nineteenth century the word went even further downhill, if that were possible, when it started to be applied in England to men who pretended to be hawkers or street traders but who were actually beggars or tramps. An early example, of 1860, is in The Roman Question, by Edmond About: “Pray give something to yonder sham cripple; give to that cadger who pretends to have lost an arm; and be sure you don’t forget that blind young man leaning on his father’s arm!”
This led a little later to the modern — mainly British — slang sense of a cadger as a man (it seems always to have been a man) who “borrows” small sums or favours from acquaintances and friends but conveniently forgets to return the cash or reciprocate — you might hear it as “he cadged a tenner off me yesterday”, or “See if you can cadge a lift to the pub”. R Austin Freeman (an almost forgotten crime writer, well-known in his day) acutely observed the type in For The Defence, Dr Thorndyke of 1934: “Ronald Barton was an inveterate cadger, a confirmed borrower; and, as is the way of the habitual borrower, as soon as the loan had been obtained, the transaction was finished and the incident closed so far as he was concerned.”
There’s also codger, which often turns up these days as old codger, meaning a man who is mildly eccentric and of mature years. This may well be a variation on cadger that comes through the idea of an old beggar or tramp (at one time in English dialect codger could refer to a disagreeable or miserly old man) but which has softened somewhat over time.
Falconers sometimes like to say that their cadge is linked to the verb to cadge and also to codger, since those who carried them were often old men good for nothing better. Though it’s true that the man who carried the cadge was indeed a cadger, there’s no direct connection between it and codger, nor with the modern sense of somebody who likes to get something for nothing.
