Morphology

shelf + life

The compound is partially compositional: 'life' denotes a duration and 'shelf' locates that duration in a storage context, so a learner can often infer it refers to how long a product remains usable on a shelf. However, the application of 'life' to products (rather than living things) and the precise sense ('suitable for use/consumption' vs. simply 'time on a shelf') is somewhat metaphorical and may not be fully predictable without exposure. Cross-linguistic expressions vary, so understanding is probable but not guaranteed for a B1 learner.

Etymology

Shelf life comes from the simple image of a product sitting on a shelf and slowly losing its life, or 'freshness', over time. So it means how long the product stays 'good to use'.
