I was searching the meanings of these two words:
alone and solo
And, (according to the source), both shares the same meaning:
alone; without other people.
Both words sounds for me interchangeable in usage "speaking, writing, etc".
As the title says: what is the difference between solo and alone? and there are rules for the usage of each one of them?
The answer should show references and example usages for learning purposes (i.e: for get a better understanting about its usage).
