Can you please check these sentences for me, please? Thank you very much.

1) The word Victorian derives from Queen Victoria, who ruled constitutionally for more than half a century, from 1837 to 1901.
2) The Victoria Age was a complex area characterized, on the one hand, by stability, inventions and great social reforms, and on the other, by poverty, injustice and social unrest.
3) The movement of Empiricism, whose major figure was John Stuard Mill, thought that progress came from mental energy, and therefore gave great importance to education and art. 4) He also promoted many reforms, such as the causes of popular education and the emancipation of women.
5) Dr Hyde is much smaller and uglier than Dr Jekyll, his alter ego. He stands for pure evil, is pale and dwarfish. His hands are dark and hairy and he gives an impression of fedormity.

All looks fine except for that last word. Is it supposed to be deformity?

Sure, I would be happy to check these sentences for you. Here are the corrections and suggestions:

1) The word Victorian derives from Queen Victoria, who constitutionally ruled for more than half a century, from 1837 to 1901.
(Note: Changed "ruled" to "constitutionally ruled.")

2) The Victorian Age was a complex era characterized, on the one hand, by stability, inventions, and great social reforms, and on the other hand, by poverty, injustice, and social unrest.
(Note: Changed "area" to "era" and added commas after "inventions" and "social reforms.")

3) The movement of Empiricism, with its major figure being John Stuart Mill, believed that progress came from mental energy and therefore placed great importance on education and art.
(Note: Corrected the spelling of "Stuart" and rephrased the sentence for clarity.)

4) He also advocated for many reforms, such as popular education and the emancipation of women.
(Note: Changed "causes of popular education" to "popular education" for clarity.)

5) Dr. Hyde is much smaller and uglier than Dr. Jekyll, his alter ego. He represents pure evil, has a pale and dwarfish appearance, and his hands are dark and hairy. He gives an impression of deformity.
(Note: Corrected the spelling of "Jekyll," replaced "stands for" with "represents," and corrected "fedormity" to "deformity.")

I hope these corrections are helpful! Let me know if you have any more questions.
