Morphology

estrogen + antagonist

The phrase is fully compositional: 'estrogen' specifies the target hormone and 'antagonist' denotes something that blocks or opposes an agent, so a learner who knows both words can infer 'a substance that blocks estrogen.' This follows a regular noun–noun medical compounding pattern that is common cross-linguistically, making the meaning predictable.

Etymology

The term estrogen antagonist paints a simple picture: estrogen is a body hormone and an antagonist is an opponent that 'blocks' it. So an estrogen antagonist is a drug that 'blocks' estrogen and is used to treat breast cancer that needs estrogen to grow.
