Morphology

be + on + one's + toe

The sense 'to be alert and ready' is metaphorically related to the literal image of standing on one’s toes (poised to move), so a learner who knows the constituents can often infer the general meaning. However, the phrase is conventionalized and metaphorical rather than fully compositional, and its pragmatic range (e.g. temporary vigilance vs. sustained readiness) is not completely predictable without exposure.

Etymology

The idiom be on one's toes may come from the simple image of standing on the tips of your toes so you can move quickly. If you are literally on your toes you can react quickly, so the phrase means 'alert and ready'.
