Where is there a list of false friends words that a beginner who's learning Esperanto from English must be aware of?
There's a rather good list of false friends on Wikibooks: https://en.wikibooks.org/wiki/Esperanto/Appendix/False_friends#English
There are quite many, but looking through them might be a good idea, even for a beginner.
David Jordan, in his book Being Colloquial in Esperanto (readable online), has written a list of "Potentially Troublesome Words", which includes false cognates with English, as well as Esperanto words that look similar to each other. And many entries include example sentences to help clarify further.
