The words 'Thespian' and "Espionage' both share a phonetic; plus both concepts share an action (skill) with each word. Investigate and may one take pleasure in learning the similarity.
The etymologies were disappointing - there was no easy jump. I was left to try playing around with the sounds in my mouth, quickly noticing how little difference there is in "theth" and "esp." Enjoyed looking up "phonetic" and its relation to this exercise.
Great suggestion. I have more questions now than before.
ThESPian & ESPionage (the sound "esp"is what I was pointing out). Now, both "professions" utilize similar skills (tools). Just keep investigating at your own pace.
