 (ăl′də-hīd′)
n.
Any of a class of highly reactive organic chemical compounds obtained by oxidation of primary alcohols, characterized by the common group CHO, and used in the manufacture of resins, dyes, and organic acids.

[German Aldehyd, from New Latin al. dehyd., abbr. for alcohol dehydrogenātum, dehydrogenized alcohol.]

aldehyde

(ˈældɪˌhaɪd)
n
1. (Elements & Compounds) any organic compound containing the group -CHO. Aldehydes are oxidized to carboxylic acids and take part in many addition reactions
2. (Chemistry) (modifier) consisting of, containing, or concerned with the group -CHO: aldehyde group or radical.
