Morphology

manway = man + way (semi-transparent) = man + way

The components 'man' + 'way' are transparent as 'person' + 'passage', but the specialized technical sense 'access opening/hatch' is domain-specific and may not be immediately inferred by general learners.

Etymology

Manway comes from the parts man ('person') and way ('path' or 'way in'). Like manhole, it literally means a 'way for a person' to enter, which is why a manway is an opening or removable cover that lets someone go inside a tank or vessel to inspect or repair it.
