First recorded in 1535–45; from Latin interceptus, past participle of intercipere “to intercept,” equivalent to inter- “between, among, together” + -cep- (combining form of cap-, stem of capere “to take”) + -tus past participle suffix; see inter-; cf. incipient

Explanation

If a national intelligence agency intercepts a telephone call being sent from one terrorist cell to another, they stop the message and also learn a bit about what's going on in the terrorist world. If you're planning a surprise party for your friend and she arrives a half hour early, you might run to intercept her while everyone rushes to hide.
