Morphology

miosis = mio (opaque) = mio + sis

The immediate base 'mio' is not a standalone English word and its meaning is not transparent to most learners.

Etymology

Miosis comes from the Greek root mei- meaning 'less' or 'to make smaller', and it names the cell process that makes the number of chromosomes smaller. So, miosis is the special cell division that produces eggs and sperm with half the usual number of chromosomes.
