Examples
“You probably feel at times like a chord of a conic section that passes through a focus and is parallel to the directrix, but know for certain that the phonemic differences between allormorphs of the same morpheme is supported by the idea that the quantitative measurement of many characters to the determination of taxa and to the construction of diagrams indicating systematic changes can make or break us.”
