A Molossus is a metrical foot used in formal poetry. It consists of three long syllables. In English poetry, syllables are usually categorized as being either stressed or unstressed, rather than long or short.
For example, the first line of the following verse is a molossus:
Break, break, break, On thy cold gray stones, O Sea! And I would that my tongue could utter The thoughts that arise in me.
and a molosser is my dog!
