Morphology

add + ballast

The meaning is directly derivable from 'add' (to put in) plus 'ballast' (weight used for stability); together they transparently denote putting weight into a vessel or structure to improve balance. This verb + object composition follows common English and cross‑linguistic patterns, so a B1 learner who knows both constituents will understand the MWE.

Etymology

Add ballast comes from old ships, where crews put heavy stones or sand called ballast in the bottom of the ship to make it steady. So today it means 'to put weight into something to make it more stable'.
