Surface Forms
Morphology
The meaning 'a crater on the surface of the Moon' is directly derivable from combining 'lunar' (relating to the Moon) with 'crater' (a bowl-shaped depression). This is a straightforward modifier + noun composition common across languages, so a B1 learner who knows both words will readily understand the MWE.
Etymology
Lunar crater comes from the words lunar (about the Moon) and crater (a bowl-shaped hole). People saw round holes on the Moon that were made when space rocks hit its surface, so the phrase means 'a bowl-shaped depression on the Moon'.
