What does galvanise mean?
To galvanise is to jolt someone — or something — into sudden, energetic action, much as an electric current shocks a muscle into movement. The word is most often applied to people and groups: a scandal may galvanise voters, a charismatic leader may galvanise a workforce, a disaster may galvanise a whole community into helping. It carries a vivid metaphor drawn from early experiments in bioelectricity, in which electrical stimulation was shown to make tissue contract, so the verb inherently suggests urgency and dramatic effect rather than gentle persuasion. 'Galvanise' is the standard British spelling, while 'galvanize' is used in America; the two are otherwise identical. Commonly paired with phrases such as 'galvanise into action' or 'galvanise support', it is a favourite of journalists and speechwriters precisely because it conveys momentum: things do not merely change after being galvanised — they spring into motion.
To shock or excite someone into taking action; to rouse to sudden activity.
"The charity's appeal galvanised donors across the country."
Almost always followed by 'into' plus a gerund when describing the resulting action, as in 'galvanised into acting'.
To stimulate muscle or nerve tissue with an electric current.
"Early physiologists galvanised severed specimens to demonstrate animal electricity."
Now largely historical or technical; this sense predates the figurative one but has been eclipsed by it in everyday use.
Every time you say 'galvanise', you're quoting an 18th-century Italian scientist who made frog legs twitch with electricity.

Etymology of galvanise
'Galvanise' takes its name from Luigi Galvani, the Italian physician who in the late eighteenth century discovered that electric sparks could make dissected frog legs twitch — an observation that helped launch the study of bioelectricity. The process became known as galvanism, and by the early nineteenth century the verb had been coined to describe both the application of such currents and, figuratively, the shocking of people into activity. The same eponym also gave English the words 'galvanic', 'galvanism', and 'galvanometer'.
