Morphology

Rigil + Kent

The constituent 'Rigil' signals a bright star, so a learner who knows that could infer the phrase refers to a star or star name; however 'Kent' has no clear lexical meaning here and offers no clue that it specifically denotes Alpha Centauri. Because this is a proper name and its precise identification (the traditional name for Alpha Centauri) is not compositional or predictable from the parts, the expression is only partially transparent to learners.

Etymology

Rigil Kent may come from old star maps that called this bright star the 'foot of the centaur.' The star sits where the centaur's foot is shown in the picture of the sky, so the name became the traditional one for Alpha Centauri.
