I want a bicycle, (a) computer and (a) guitar. <br/><br/>Is it necessary to have an article before every noun? <br/><br/>I'm also very confused on when to use 'the'. <br/><br/>Thanks a lot <img class='emoticon' style='Width:19px;Height:19px;' data-delaysrc='https://uat-englishforward-forums-backend.s3.us-west-2.amazonaws.com/Emoticons/1.gif' src='https://uat-englishforward-forums-backend.s3.us-west-2.amazonaws.com/Emoticons/1.gif' alt='Emotion: smile'/>
