Mina Loy
Shafer Hall

Here lies my Renee Lenore breathing
All over my pillow; woman poets make her pink.
I blush when I think about how we educated each
Other in:

friction or rustling of the breath, intonated or
untonated, through a narrow opening between
two of the mouth organs; uttered through close
approach of the organs of articulation,

-- said of certain consonantal sounds

Mina Loy defined fricative a million times.
