gall Scientific  

/ gôl /

1. An abnormal swelling of plant tissue, caused by injury or by parasitic organisms such as insects, mites, nematodes, and bacteria. Parasites stimulate the production of galls by secreting chemical irritants on or in the plant tissue. Galls stimulated by egg-laying parasites typically provide a protective environment in which the eggs can hatch and the pupae develop, and they usually do only minor damage to the host plant. Gall-stimulating fungi and microorganisms, such as the bacterium that causes crown gall, are generally considered to be plant diseases.

Etymology

Origin of gall¹

First recorded before 900; Middle English galle, gal “gallbladder; bitter taste; rancor; poison,” Old English gealla “bile”; cognate with German Galle; akin to Latin fel, Greek cholḗ, chólos “gall, bile”; gall ² ( def. )

Origin of gall²

First recorded before 1000; Middle English gal(l)e, gaul(e) “sore (on the skin); stain, impurity; barren spot (in a field),” Old English gealla “an abrasion or sore (on a horse)”; possibly from Latin galla “nutgall”; possibly the same as gall ¹ ( def. ), the senses developing from “bile” to “poison” to “(poisonous) sore” to “stain”; gall ³ ( def. )

Origin of gall³

First recorded in 1350–1400; Middle English galle, from Middle French, from Latin galla “gallnut”; gall ²

Explanation

Gall describes something irritating, like someone very rude. If you barge into a bakery and cut in front of a sweet old lady, then you have gall. If someone has gall, they're irritating. In fact, as a verb, gall means "to irritate" like new tight jeans that gall your thighs. Gall is "bile," too, like what's in a gall bladder. Back in the days of Hippocrates, if the four humors of the body were out of whack, it affected your spirits. If you had too much bile, or gall, then you'd be aggressive or depressed. It's also a noun for "deep feeling of ill will."
