Final answer:
The statement about 'Bastille' being an alternative spelling of 'Bastida' and about the verb 'embastiller' is false. 'Bastille' refers specifically to the Parisian fortress-prison stormed during the French Revolution.
Step-by-step explanation:
The claim that 'Bastille' is an alternative spelling of 'Bastida' (built) or the French 'Bastide,' meaning fortification, and that the verb 'embastiller' means to garrison troops in a prison is false. The term 'Bastille' refers specifically to a fortress-prison in Paris that played a significant role during the French Revolution. It was stormed by the people of Paris on July 14, 1789, which became a pivotal event in the revolution, leading to the fall of the French monarchy. The capture of the Bastille is commemorated annually on Bastille Day, a national holiday in France.
