Morphology
Eocene = eo + cene
The name is built from Greek combining forms (eo- 'dawn' + -cene 'new') that are technical and not productive standalone English words, so an average learner cannot derive the meaning from the parts.
Etymology
Eocene comes from Greek roots Eo- meaning 'dawn' and -cene from kainos meaning 'new'. So, Eocene is like the 'dawn of the new' — the time when many modern mammals first appeared.
