this morning I woke up naturally, almost ten o'clock, pretty luxurious
this morning I woke up naturally, almost ten o'clock, pretty luxurious

I want to say that I didn't set an alarm clock, I wake up til I have enough sleep.
1. Is "naturally" here clear enough?
2. I use "luxurious" here to describe this was a rare experience/ opportunity. (like buying something very expansive..). Is it weird to use this word?I chose the wrong category of this question, I chose " learning Mandarine." Don't know how to fix it...

Answer

I think naturally suits this sentence pretty well but the usage of the word "luxurious" is a bit weird to me......perhaps "unusual" will be a better fit? Or if you felt good about waking up by yourself at 10 o'clock then maybe "remarkable" can be a better alternative?

Answer

for first question I think at 10 o'clock the waking up is unusual I mean that you wake up early every day but when you didn't set alarm you were late.if you wake up at 10 oclock every day by  alarm and this morning wake up without it we say you wake up naturally without help

Answer

I'm not a native English speaker, but "naturally" seems to be a good fit here for me. For "luxurious", it sounds a bit strange but mostly because it's missing a verb for me - unless you were writing a Tweet. How about "it felt pretty luxurious"? Or "such a luxury"?
