CIDE DICTIONARY

Accessory, a. [L. accessorius. See Access, and cf. Accessary.].

 Accompanying as a subordinate; aiding in a secondary way; additional; connected as an incident or subordinate to a principal; contributing or contributory; said of persons and things, and, when of persons, usually in a bad sense; as, he was accessory to the riot; accessory sounds in music.  [1913 Webster]
" Ash accents the antepenult; and this is not only more regular, but preferable, on account of easiness of pronunciation. Most orhoëpists place the accent on the first syllable."  [1913 Webster]
