N: 1. c.1600, from Modern Latin, from Greek pneumonia “inflammation of the lungs,” from pneumon “lung,” altered (perhaps by influence of pnein “to breathe”) from pleumon “lung,” literally “floater,” probably cognate with Latin pulmo (see pulmonary), from PIE *pleu- “to flow, to swim” (see pluvial). Alteration in Greek perhaps by influence of pnein “to breathe.”
2. pneumonia, inflammation and consolidation of the lung tissue as a result of infection, inhalation of foreign particles, or irradiation. Many organisms, including viruses and fungi, can cause pneumonia, but the most common causes are bacteria, in particular species of Streptococcus and Mycoplasma. Although viral pneumonia does occur, viruses more commonly play a part in weakening the lung, thus inviting secondary pneumonia caused by bacteria. Fungal pneumonia can develop very rapidly and may be fatal, but it usually occurs in hospitalized persons who, because of impaired immunity, have reduced resistance to infection.
3. Collocations:

• Adj. severe | bronchial, double | bacterial
• Quant. bout
• Verb + pneumonia: have, suffer from; catch, contract, develop, get; die from/of; cause.

4. Cultural Interrelation: Carl Sagan (1934-1996), Billy Wilder (1906-2002), Gabriel Garcia Marquez (1927-2014) and Bob Hoskins (1942-2014), among other personalities, died of pneumonia.
