Morphology

backbone + of

The sense 'the most important support or foundation' is directly derivable from 'backbone' (chief support/strength) combined with the relational preposition 'of' specifying what is supported; this follows a standard, compositional noun + of pattern. The metaphorical use is common and cross-linguistically mirrored, so a B1 learner who knows 'backbone' would readily infer the MWE meaning.

Etymology

The phrase backbone of comes from the body's spine. The backbone is the main bone that holds the body up and gives it strength, so calling something the backbone of a team or project means it is the main 'support' or 'foundation' that everything depends on.
