The term 'put in writing' can be expressed in a variety of ways. The three-letter word 'PEN' is often used to refer to the act of writing, as it is a tool used to physically write words on paper. The seven-letter word 'scriven' is an archaic term meaning to write or compose. The six-letter word 'INDITE' is another verb meaning to write or compose, while the seven-letter word 'indited' is the past tense of the same verb. All of these words refer to the act of putting something in writing, either through physical writing or composition.
