A trochaic foot (trochee) has a long syllable followed by a short syllable (LS or /U).
Dimeter is two feet per line.
Poems written entirely in trochaic dimeter must be very rare – we were unable to find an example! Please let us know if you find one.
However, if trochaic dimeter poems do exist, they must be something like this (stressed syllables in bold type):
Up the mountain,
Down the valley,
Train chugs onward.
The word “steadily” has two accented syllables, “stead” and “ly”. The “i” in the middle is unstressed.)
