Use of Indefinite Articles 'a' and 'an' in the Forum Titles / PostsIt is being observed that the indefinite articles 'a' and 'an' are not being used the right way in the Forum posts / titles.
There is a general rule that the article 'an' is used for the words starting a vowel (a, e, i, o, u). Accordingly members are using 'an' for the words that start with a vowel. So also members use the indefinite article 'a' for every word that starts with a consonant (i.e letters other than the vowels).
Please note that there is an exception for this rule.
The pronunciation of the word is taken into consideration for using indefinite articles 'a' and 'an'.
a uniform, a unit, a university, a utensil, a unique, a union
- in these words the pronunciation of the 1st letter 'u' (though a vowel) is that of a consonant i.e 'y'. Accordingly article 'a' is used for these words.
Note that article 'a' is not used for all the words that start with the vowel 'u'. Example: it is an umbrella, an ugly and not a umbrella, a ugly.
Words that start with a vowel but do not take the indefinite article 'an' are:
'a euro', a European etc.
There are words that start with a consonant but the 1st letter is pronounced as a vowel. For such letters, indefinite article 'an' is used. Examples of such words: an hour, an year, an honor, an honorary, an honest etc.
