An acephalous or headless line is a variety of catalectic line in a poem which does not conform to its accepted metre, due to the first syllable's omission. [1] Acephalous lines are usually deliberate variations in scansion, but this is not always obvious.
It is a technique employed often in the concluding lines of hymn texts, and has been employed in poetry to change tone or announce a conclusion, including its use in A. E. Housman's " To An Athlete Dying Young." [ original research?] Robert Wallace argues in his essay " Meter in English" that the term acephalous line seems "pejorative", as if criticising the poet's violation of scansion, but this view is not widely held among critics. [2]
Acephalous lines are common in anapestic metre, especially in limericks.
The third line is scanned x ' x x ' instead of x x ' x x '.
