Pick up on something
Meaning
To notice or become aware of something, often subtly or indirectly.
Origin
The phrase 'pick up on something' solidified its meaning in the 20th century, drawing its imagery from the physical act of gathering or intercepting. It evokes the delicate attentiveness of a radio operator 'picking up' a faint signal, or a hunter 'picking up' the subtle tracks of an animal. This notion of keenly observing and mentally retrieving an otherwise missed detail, transforming a physical act of collection into a cognitive one, perfectly captured the nuance of becoming aware of something indirect or implied in a situation.
Examples
