how to understand this sentence ?

[AUTOMOON]

[Tdol]

It means that when the person was free they spent their time listening to Enya's music.

[AUTOMOON]

It means that when the person was free they spent their time listening to Enya's music.

you told me the meaning of this sentence ,but what about the
grammer points ?
some people told me that , there should be an comma between HAD and ENYA , and that , the propositon "at" is omitted before that time , so the
object of the sentence is THE FREE TIME, and the adverbial part is (at) that time,"I had ,Enya had " serves as adjective part for the object .
What is your opinion ?

as this : The free time I had , Enya had , at that time .

[Tdol]

I'd just put a comma in the middle. You can add 'at, but it isn't necessary. If you do, then a second comma would make sense.

1. Yes, you put a comma after the first "had" but not the second, and you don't add "at".
2. The sentence means "Enya had that time" and "that time" is "the free time I had".
3. Another way of saying it is: Enya had the free time that I had.

I was just so surprised to get another explanation that long after. :P

Good to come back too! Yes, had a look at your stats. Compared to say, Englishclub, your site offers really good features - ease of usage, interaction at much greater convenience, a more open forum compared to a one-to-one exchange. Am sure you will keep growing.

Will be away again, but will always be back again, and again. :wink:
