• noun whence in English -al is now applied to Latin adjectives ending in -e-us, -i-us, -u-us, -rn-us, -i-s, -ic-us, etc., to give them a distinctive English form, as in aerial, senatorial, perpetual, eternal, celestial, medical, etc., and similarly to Greek adjectives in -ικ-ός, -ακ-ός, -οειδ-ής (English -ic, -ac, -oid), etc., as in musical, heliacal, rhomboidal, etc.; hence in some cases a differentiation of meaning, as in comic and comical, historic and historical, etc.

• noun A nominal prefix, actually a reduction of alcohol in certain arbitrary formations, as aldehyde (and its numerous recent derivatives), *althionic, etc. Compare -al.

• noun The name is applied in India to several species of Morinda, especially to Morinda citrifolia and M. tinctoria, trees belonging to the madder family, which grow spontaneously and are also cultivated for the sake of the dye obtained from the bark of their roots and stem. The smallest roots yield the most valuable dye, the stem the most inferior. The al dye is gradually supplanting the more expensive red obtained from the Indian madder, or chaya root (Oldenlandia umbellata), with which the celebrated Madras handkerchiefs and turbans were formerly dyed. Morinda citrifolia, the principal al-tree, is widely spread throughout the East Indies, the west coast of Africa, and the islands of the Pacific Ocean, where its fruit is sometimes eaten by the natives.
