The term 'HARPLIKE INSTRUMENT' can be solved by the 4-letter word 'LYRE'. The LYRE is a stringed instrument that has been used since ancient times. It is similar to a harp in that it has strings stretched across a frame, but it is smaller and more portable. The LYRE is often associated with Greek mythology and was used by the gods and goddesses of Olympus. It is still used today in folk music and other genres.
