Surface Forms

Morphology

transplacental = placental (transparent) = trans + placenta + al

Formed by straightforward prefixation of 'trans-' ('across/through') to 'placental' ('relating to the placenta'), yielding 'through or across the placenta'.

Etymology

Transplacental comes from trans- meaning 'across', as in transfer, and placenta meaning 'the organ that feeds the baby in the womb'. So it describes something that moves 'across the placenta' from the mother to the baby before birth.
