It depends.Hello all.
Which is correct?
... a 8-meter long table
an 8-meter long table?
...We use an before a vowel sound: does that help?
Keep in mind that it's before a vowel sound, not necessarily before a vowel. As the first quoted poster posted earlier today in this thread, an example is "university." It begins with a vowel but is pronounced as if it started "Yoo..." We say "a university," not "an university."...I'll never forget that rule anymore...
