Certainly! Here's a way to get from "REACH" to "GRASP":
REACH -> PEACH -> PEACE -> PLACE -> PLAGE -> PAGES -> PASES -> PARES -> PARSE -> GRASP
Each step involves changing just one letter and every word in the sequence is a valid English word. Note that "PLAGE" is a less common word, referring to the sandy shore of the sea or of a lake that is used as a bathing beach.
