Question

Articles

Gold is an useful metal ​

Answer 1

Articles 'a', 'an', and 'the' are used before nouns considering many rules in mind. One of the rules is the rule of consonant and vowel. While using articles we follow the 'sound rule' in mind. If the sound is vowel, we will use 'an' while using indefinite article. If the sound is consonant, we shall use 'a'. Some words starting with vowel make consonant sounds. Words such as 'university', 'useful', 'unique', 'unicorn', etc. also fall in the category of words that start with a vowel letter; but their sound is consonant. Hence we use 'a' in front of these words.

The given sentence will be written as shown below:

Copper,Gold is a useful metal.
