Morphology

2nd + childhood

The phrase literally combines 'second' (another) and 'childhood', so a B1 learner who knows the constituents can infer 'a second period of being a child'. However, the conventional sense — a metaphorical, age-related regression or mental decline in old age — is an idiomatic extension that requires cultural/figurative knowledge beyond literal composition, making the meaning only partially predictable.

Etymology

Second childhood paints the image of someone having a childhood a second time later in life. So it is used to say a person becomes 'childish' again when they get old.
