Morphology
The meaning is directly and transparently built from 'prime' (peak period) + 'of' + 'life' (the span of a person's existence), so a learner who knows these words can infer it refers to the peak period of one's life. This is a straightforward compositional noun phrase and aligns with cross‑linguistic patterns, making it immediately comprehensible at B1.
Etymology
Prime of life comes from the picture of prime as the very best part and life as a person's years, like someone who is strong and full of energy. That's why it means 'the best time in a person's life', when they are at their peak.
