Morphology

intertidal = tidal (transparent) = inter + tide + al

Formed by prefixing 'inter-' to the adjective 'tidal' (itself tide + -al), giving the literal meaning 'between tides' which is predictable from the parts.

Etymology

The word intertidal comes from inter- meaning 'between' and tide meaning 'the rise and fall of the sea'. So intertidal describes the part of the shore that is 'between tides', sometimes dry at low tide and covered at high tide.
