Surface Forms

Morphology

turn + (something) + upside + down

The meaning builds on the clear literal sense of 'turn' + 'upside down' (to invert something), and the figurative sense 'cause a dramatic change or disruption' is a predictable metaphorical extension of physical inversion. Because the idiomatic reading follows transparently from the literal image but still requires recognizing a metaphorical shift, it is not fully compositional for all learners.

Etymology

Turn (something) upside down comes from a simple picture: if you turn a box upside down, the things inside fall out and get mixed up. So, to 'turn something upside down' now means 'to cause a big change' or 'to create confusion'.
