chlorosisn.

Brit.

/kləˈrəʊsɪs/,

/klɔːˈrəʊsɪs/, U.S.

/klɔˈroʊsəs/

Inflections: Plural chloroses.

Origin: A borrowing from Latin Probably also either (i) formed within English, by derivation. Or (ii) a borrowing from Greek, combined with an English element. Etymons: Latin clorosis ; chloro- comb. form¹, -osis suffix; Greek χλωρός , -osis suffix.

Etymology: In sense 1 < post-classical Latin clorosis ( J. de Varanda De morbis et affectibus mulierum (1619) i. i. 5) < ancient Greek χλωρός green, greenish-yellow, pale green (see chloro- comb. form¹) + -ωσις -osis suffix. Compare French †chlorosis (1694), chlorose (1753). Compare also earlier green sickness n. In sense 2 probably an independent formation < chloro- comb. form¹ or its etymon ancient Greek χλωρός + -osis suffix; it seems unlikely that sense 2a was suggested by sense 1, since the human disorder is characterized by the acquisition of a greenish pallor, while the plant disorder involves loss of green coloration.

1. Medicine. A disorder believed to occur almost exclusively in young, virginal women soon after puberty, characterized by a greenish pallor of the skin, cessation or irregularity of menstruation, and weakness, often accompanied by pica or other disturbance of appetite; an instance or case of this. Also called green sickness. Now historical.As a medical diagnosis chlorosis disappeared quite abruptly in the early part of the 20th cent. Modern medical writers have most commonly identified it as a form of iron-deficiency anaemia with a profoundly reduced haemoglobin level, thought to result from combined dietary iron and protein deficiency. More recently it has been pointed out that various other disorders, esp. anorexia nervosa, may produce symptoms similar to those of chlorosis, and that social and cultural attitudes towards women and menstrual physiology may have played an important role in the designation of chlorosis as a distinct clinical entity.

2. Botany.

a. The loss of the normal green coloration of leaves of plants (esp. as a symptom of disease or disorder), caused by conditions which reduce or prevent the formation of chlorophyll, such as iron deficiency in lime-rich soils, disease, or lack of light (cf. etiolation n. 1).
