Morphology

level + best

The core meaning 'greatest effort' is clearly signaled by 'best', but 'level' here functions as an idiomatic intensifier rather than its literal sense of 'stage' or 'flatness', so the exact phrasing is not fully compositional. A B1 learner who knows 'best' and the common pattern 'do one's best' can probably infer the meaning from context, but the non-literal contribution of 'level' makes it only partially predictable.

Etymology

Level best may come from the picture of raising your effort to the highest level and giving your best there. So doing your level best means giving the 'greatest effort' you can.
