Root Explanation

Menstruum is derived from the Latin "mensis" (meaning month) and the suffix "-trum" (indicating a means or instrument). The term originally referred to a monthly cycle, particularly in relation to the menstrual cycle, and has come to denote a solvent or medium in which substances are dissolved.

Memory Tip

Think of the word 'month' ('mensis') to remember that 'menstruum' relates to a cycle, particularly the monthly cycle, and also serves as a medium for dissolving substances.
