Morphology

antigenic + determinant

The phrase is a straightforward adjective + noun composition: 'antigenic' (relating to antigens) qualifies 'determinant' (a specific part or region), so the meaning 'the specific part of an antigen that an antibody binds' is directly derivable from the constituents. Although the term is technical and low-frequency, its structure follows normal English compounding and similar constructions exist cross-linguistically, so a learner who knows both words can infer the overall meaning.

Etymology

Antigenic determinant creates a simple image: an antibody is like a key and the determinant is the tiny 'lock' on the antigenic surface that the key fits. So it means the 'specific part of an antigen that an antibody binds to'.
