Surface Forms

Morphology

out + of + the + side + of + one + mouth

The phrase literally describes producing sound 'out of' the 'side' of one's 'mouth', so a learner who knows those words can plausibly infer a quiet, indirect or discreet manner of speaking. The meaning is a direct, image-based extension of the constituent words (speaking from the side reduces volume and visibility) and this bodily metaphor is common cross-linguistically, making it readily understandable to B1 learners.

Etymology

The phrase out of the side of one's mouth comes from the picture of someone speaking through the side of their mouth so the words are soft and hard to hear. So, it now means 'in a quiet or secret way', often to avoid being noticed.
