Cambridge: The book presents a one-sided view of history.

I'm confused. I thought that it should be an one-sided view of history. Could you please explain this case to me?

I know that the article is for the noun (view) not for the adjective (one-sided) but I was told that even if a word starts with a consent which sounds like a vowel, it should be preceded with "an" not "a". So I always thought the grammar rule is based on a vocal need. What I mean by this is that it is easier for Native English speakers to say "an" one-sided instead of "a" one-sided.

    @Davo So it is "an online application" because "online" starts with "o" sound and it is "a one-sided view" because one starts with "wa" sound ? – Costa Nov 8 '19 at 15:08

    @Costa - You got it. I would be a one-sided view, but an eight-sided view. – J.R. Nov 8 '19 at 15:13
