Morphology

under + someone's + nose

The phrase literally expresses spatial proximity ('under' + 'someone's' + 'nose'), so the basic sense of something being very close is directly derivable from the constituents. However, the idiomatic extension that this closeness occurs 'without their knowledge' requires a pragmatic/ironic inference rather than strict compositionality, so a B1 learner may not fully predict the unawareness component without exposure.

Etymology

The idiom under someone's nose comes from the simple image of something lying under a person's nose while they do not see it. So it now means 'in someone's presence or nearby without them noticing'.
