IPA: //sʌbˈmɑːrdʒɪnəl//
KK: /sʌbˈmɑrdʒɪnəl/
Referring to something that is located near the edge or border of a body or part, or something that has low productivity or is below a necessary minimum.
The submarginal land was not suitable for farming due to its poor soil quality.
Submarginal → It is formed from "sub-" (meaning under or below) and "marginal" (from Latin "margo", meaning edge or border). The word "submarginal" refers to something that is below the margin or edge, often used in economic contexts to describe land or resources that are not fully productive.
Think of something that is 'under' ('sub-') the 'edge' ('marginal') — that's why submarginal refers to something that is below the productive level.
