Cadge is a verb that means to beg.
The linguistic origin of cadge is not known for certain, but we do know that in the 1400s, peddlers who were called cadgers travelled the British countryside with horses and carts. By the 1800s the term was often used to describe people who were beggars posing as peddlers.
I hate having to cadge money from my brother. He always makes me feel bad for having to bed.
