mer-JEL-us

Genus

The little diving bird

Literally: A little diver

PartMeaningLanguageNote
merg- A diver; from mergere, to dive or dip Latin (=mergus) Stem of classical Latin mergus, a diving seabird; -us dropped before the diminutive suffix
-ellus Diminutive suffix Latin (-ellus, =ella, =ellum) Marks the whole word as masculine; produces a new masculine Latin noun

Mergellus is a single masculine Latin noun formed by attaching the diminutive suffix -ellus directly to the stem merg- of the classical Latin noun mergus ('a diver'). The geminate -ll- is characteristic of this suffix. As a genus name it stands alone; the species epithet (e.g. albellus) would agree with it in gender (masculine).

  • mer-JEL-us Penult rule 5: the penult vowel e is short and followed by two consonants (ll), so the penult is stressed. The g is soft (j) before e by the c/g-before-e rule.

Commonly: mer-GEL-us is also heard in ornithological usage, applying a hard g as if it were a geminate Latin stop rather than applying the soft-g-before-e rule.

One could parse merg- as the bare verbal root (mergere, 'to dive/dip') rather than the nominal stem of mergus; the meaning is identical either way.

The dictionary contains both the verbal root merg ('dive, dip') and the standalone noun form =mergus ('a diver'); the noun form is the more direct source of the genus name. The diminutive suffix -ellus is confirmed in the dictionary both as a standalone form (=ellus, meaning 'small') and explicitly as a diminutive suffix (-ellus, =ella, =ellum). Mergellus albellus (Smew) is the smallest member of the merganser tribe, making this diminutive name particularly apt.
