Morphology

prolactin = lact (semi-transparent) = pro + lact + in

The prefix 'pro-' suggests promoting or supporting, and 'lact' relates to milk production, but the specific hormone function is specialized knowledge.

Etymology

Prolactin comes from the parts pro- ('for') and lact- ('milk'), with -in a common ending for many substances. So prolactin literally means 'for milk' and is the hormone that helps the body make milk after childbirth.
