Morphology
tell + tale + out + of + school
The components 'tell' and 'tales' transparently signal telling stories or gossip, so a B1 learner might infer it's about saying things about others; however the fixed phrase 'out of school' and the specific sense of indiscreetly revealing private or confidential information is idiomatic and not fully predictable from the parts. Because part of the meaning is inferable (telling stories/gossip) but the precise pragmatic sense (improper disclosure) requires prior exposure, the expression is best classified as semi-transparent.
Etymology
Tell tales out of school may come from a simple image: children who heard or shared something in class then tell tales out of school, taking those stories outside where they did not belong. So, the phrase now means to reveal 'private' information.
