Morphology

isotonic = tonic (semi-transparent) = iso + ton + ic

The prefix 'iso-' means equal, and 'tonic' relates to tone, but understanding the specific application to osmotic pressure requires specialized knowledge.

Etymology

Isotonic comes from Greek parts iso- meaning 'equal' and tonos meaning 'tone' or 'pressure', a meaning you can link to the common word tone. So an isotonic solution has the same 'pressure' as your body fluids, which helps keep fluids and cells in balance.
