不仅
bù jǐn
not just; not limited to
(as a correlative conjunction) not only (..., but also ...)
not (不) + merely (仅) = not only, not limited to
不 negates and 仅 means 'only' or 'merely', so together they push past a single boundary. The phrase signals that more is coming — a correlative like 也 or 而且 often follows to complete the thought.

tā bù jǐn huì chàng gē, hái huì tiào wǔ.
she not only can sing, but also can dance.
