Etymology
The word 'expectorant' is a direct borrowing from Latin expectorant-, the present participle stem of expectorare, meaning "to banish from the breast or mind." This Latin verb is a compound of the prefix ex- ("out") and pectus ("breast, chest"). The literal sense was "to expel from the chest." In medical terminology, it was adopted in the 18th century to specifically denote substances that aid in expelling mucus from the lungs and airways. Thus, the modern term retains the original Latin logic, describing an agent that facilitates the action of bringing material out from the chest.
Analysis
