Morphology
Tarchanoff + phenomenon
The word 'phenomenon' signals that this is an observable effect, so a B1 learner who knows 'phenomenon' can infer it is a named effect or occurrence. However, 'Tarchanoff' is a proper name with no lexical meaning for learners, so the specific content (skin electrical changes in response to stress) is not derivable from the parts; the expression is therefore only partially predictable.
Etymology
Tarchanoff phenomenon comes from a scientist named Tarchanoff who noticed that the skin makes tiny electrical changes when a person feels stress or fear. Think of the skin like a small battery that changes when you are nervous, so the phrase now means those electrical changes in the skin linked to 'anxiety' or 'stress'.
