Morphology
The literal composition ('kill' + 'fatted' + 'calf') clearly evokes slaughtering a well‑fed animal for a special meal, so a learner who knows the words can infer a connection to feasting or celebration. However, the phrase functions as a culturally specific idiom (Biblical/proverbial background) meaning 'to welcome or celebrate someone with lavish hospitality,' which is a pragmatic extension not fully predictable for a B1 learner without exposure.
Etymology
The idiom kill the fatted calf comes from an old story where a father kept a special fat cow, the fatted calf, and would kill it to make a big feast when his child came home. That's why the phrase now means 'to celebrate' or 'welcome someone with a big party'.
