The solution: Article A must be used in front of a name beginning with a 'consonant' sound and 'AN' in front of a name beginning with a 'vowel' sound. Examples: - door (door)> a door / d / is a consonant sound - apple (apple)> an apple (an apple) / a / is a vowel sound - kitchen (kitchen)> a kitchen (a kitchen) / k / is a consonant sound xceptions: 1) In front of the sound / j /, we use A and not AN. Example: a union (this word starts with the sound / j / Listen to it: But by the way, what is 'the sound / j /?' This is the sound we find at the beginning of: 'yellow', 'United States' ... WARNING! It is a phonetic symbol and not the letter J. We find a close sound in French at the beginning of the word 'Yogurt': the sound 'ye' 2) For words beginning with 'h', one must ask whether it is pronounced (aspirated) or not: If the 'h' is sucked, the word starts with a consonant sound. So we use A: A horrible war. If the 'h' is not sucked, the word does not start with a consonant sound, so we use AN: an hour. Then perform various exercises. Example of a beginner's course.
