According to the dictionary claims,
A good feature that makes something better than similar things.
And also, virtue means:
a. The virtue of something is an advantage or benefit that it has, especially in comparison with something else.
b. A virtue is a good quality or way of behaving.
Despite the wording style of the dictionaries, I don't see much difference between these two words in one of the following sentences, but it strikes me as if they cannot be swapped in two cases! Please have a look on my examples and their relevant explanations:
- Your advantage / virtue over him is your higher educational degree.
Explanations: here I think that "virtue" doesn't work here, while it can only refer to the "moral" aspects of someone.
- One of the advantages / virtues of the electricity over gas is the lack of fumes.
Explanations: here the two nouns can be used interchangeably for me.
- Patience is one of his advantages / virtues.
Explanations: I think these two words do not convey the same message here, while the stand-alone virtue alludes to the moral quality of someone that put they in a higher position comparing another person/people and "advantage" cannot indicate such a message by itself, unless I change it to "moral advantage".
Do you confirm my interpretation in the above-mentioned sentences? If not, then please let me know why?
