Rebus Principle
Definition - Coining a word by co-opting existing symbols purely for their sounds regardless of their meaning.

Example -
Many ancient writing systems used the Rebus Principle to represent abstract words, which otherwise would be hard to represent by pictograms. For example, representing the sentence “I can see you” by using pictograms for eye + can + sea + ewe.

Etymology -
The word rebus — which in Latin means "by things" — denotes a type of word puzzle where pictures are used to represent words or parts of words. For example, H + {a picture of an ear} represents the word hear.
