The fifth foot, therefore, is almost always a dactyl whereas the sixth foot consists of a spondee; this line ending is perhaps the most notable feature of the meter.
The spondee threshold test is a related test that detects the loudness at which the participant is able to repeat half of a list of two syllable words or spondees.
There is generally one accent in each foot of a line, unless the foot is a spondee (//).
The other feet can be varied with a spondee, dactyl, tribrach, or more rarely an anapaest.
The spondee typically does not provide the basis for a metrical line.
The sixth foot is either a spondee or a trochee.
This term suggests a line of six dactyls, but a spondee can be substituted in most positions.
These equivalences allow for easy substitutions of one foot by another e.g. a spondee can be substituted for a dactyl.
