are phonetic constituents that distinguish between phonemes (p. 77). Certain sound properties might be similar between phonemes, others dissimilar. Take [m] and [n] as examples. Both are similar in respect to manner of articulation, both are nasals. However, they are dissimilar in respect to place of articulation, bilabial in the case of [m], alveolar in the case of [n]. These dissimilar features establish [m] and [n] as separate phonemes of General American English. Distinctive features are used to analyze these similarities and dissimilarities. Distinctive features were envisioned as a means to categorize all the speech sounds in all the languages of the world.

Distinctive features are phonetic constituents that distinguish between phonemes.

Explanation:

Distinctive features are the most basic unit of phonological structure that can be analyzed. They concern classes that distinguish between phonemes such as manner and place of articulation. A different example than the one given in the question would be between the phonemes t and d. They are both alveolar phonemes - meaning the tip of the tongue touches the gum behind the front teeth. The distinctive feature between them is the fact that t is voiceless while d is voiced. That is, t does not use the vocal cords while d does.
