Morphology
isochron = iso + chron
Formed from Greek combining forms iso- ('equal') + chron ('time'); the components hint at 'equal time' but they are not standalone English words and the term is technical, so learners may only partially infer the meaning.
Etymology
Isochron comes from the Greek parts iso- meaning 'equal' or 'same' and -chron meaning 'time', like in synchronize where things happen at the 'same time'. So an isochron is a line that joins points on a map or diagram that are the same in time or age.
