Morphology
eutectic = eutect + ic
A technical term built from Greek combining elements (rendered here as 'eutect' + '-ic'); the components are not productive English morphemes for average learners, so the meaning is not derivable from familiar English words.
Etymology
Eutectic comes from Greek parts eu- ('good' or 'well') and tēkein ('to melt'), so it literally means 'well-melting'. So a eutectic mixture is one that 'melts well' at a single, lower temperature than its separate parts, which is why the name fits its behavior.
