Morphology

mainstay = main + stay (semi-transparent) = main + stay

The components 'main' + 'stay' are clear, but the figurative extension to 'the central support or source of strength' is a metaphorical generalization that may not be fully predictable for all learners.

Etymology

Mainstay comes from main ('main' or 'most important') and stay ('support' or 'rope'). It was first the rope that held a ship's main mast, so today a mainstay is the most important support of a person, group, or thing.
