Surface Forms

neodymium singular
neodymiums plural

Morphology

neodymium = didymium (opaque) = neo + didymium

Formed from Greek combining forms used in chemical naming (neo- + didymium + -ium); this construction and historical reference are not transparent to average learners.

Etymology

Neodymium comes from the Greek parts neo- 'new' and didymos 'twin', because scientists found it as a 'new twin' of a similar element. So its name means 'new twin', and today neodymium is the name of a rare-earth metal used in very strong magnets and lasers.
