Morphology

tropic + of + Cancer

Given a learner who knows 'tropic' (one of the two 23.5° latitude parallels) and 'Cancer' (the constellation/astrological sign), the phrase 'Tropic of Cancer' transparently denotes the tropic associated with Cancer — i.e., the northern 23.5° parallel. The composition 'tropic of X' is a regular, cross-linguistic naming pattern, so the overall meaning is directly derivable from the parts.

Etymology

The Tropic of Cancer gets its name from old words: Tropic means 'turn' because the sun seems to stop and 'turn' back there, and Cancer means 'crab', the group of stars the sun was in long ago. So the name marks the line north of the Equator where the sun can be 'directly overhead' in June.
