Answer:
Start with The Alphabet
Step-by-step explanation:
It's the best way to begin, although your english look's pretty good already you also need to know when letters are silent and how some have more than one sound.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Vowels are A, E, I, O, U
All others are constants.
Pterodactyl is a example, the P is silent.
