To each of the above 5-letter words add two additional two letters, not existing in the word, then permute the 7 letters to form a new non-esoteric English word, e.g. TRAIN+HS=TARNISH or TRAIN+CG=TRACING.
Never add 2 letters that were used before, thus utilizing all 26 letters to fully perform the task.
