Morphology

in + flagrante + delicto

The phrase is a fixed Latin legal/idiomatic formula whose key constituents ('flagrante', 'delicto') are not English words and carry no transparent meaning for a typical B1 learner. Knowing only 'in' would not allow derivation of 'caught in the very act'—the phrase functions as a borrowed idiom and requires prior exposure or translation, so it is opaque.

Etymology

In flagrante delicto comes from Latin words flagrante meaning 'burning' and delicto meaning 'crime', which create a sharp picture of someone caught while the bad act is still happening, as if the crime were 'on fire'. That's why the phrase now means being caught 'in the very act' of wrongdoing or in a compromising situation.
