Explanation:
Any non-native English speaker can tell you that learning English is not easy. Between complex grammar structures, confusing idioms, and difficult English pronunciation rules, English can be a lot to handle. Thankfully, there is a method to the madness.
Like any language, English relies on a set of rules that dictate the order and sound of words. Unfortunately, there is no shortcut to learning all of these rules. It takes years of study and practice; and the earlier you start, the better.
Most students agree that English pronunciation rules are some of the toughest rules to learn. So, to help you improve your English pronunciation, we have provided the following guide on English pronunciation rules and how to learn them. Let’s begin with some of the most basic English pronunciation rules:

First, it is important to know the difference between pronouncing vowels and consonants. When you say the name of a consonant, the flow of air is temporarily stopped (which means that your tongue, lips, or vocal cords quickly block the sound). However, when you say the sound of a vowel, your mouth remains open, and the flow of air does not end until you stop speaking.
Vowels – a, e, i, o, u, *y, *w
Consonants – b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, *w, x, *y, z
*It is important to note that -w and -y can act as either vowels or consonants, depending on the combination of letters in each word. For example, the word “day” uses the vowel form of -y, while “yell” uses the consonant form. Similarly, “owe” uses the vowel form of -w, while “work” uses the consonant form.
Once you learn the name and basic sounds of each letter, you can start to put them together to form words. For example, the letters p, e, and t come together to form the word “pet.”

Usually, one vowel is surrounded by consonants in a word (example: pet). However, in many words, two vowels are put together, creating an entirely new sound. When this happens, the first letter of the combination is usually long, while the second letter is silent. Here are a few examples: ai (daily), ea (eat), ie (pie, outside), oa (boat), ay (say), oo (choose, book), and ee (feel).

Just like vowel combinations, consonant combinations can create entirely new sounds. Sometimes, these sounds are a combination of each individual letter (like -ct in the word “act”), but sometimes they are completely unrelated to the sounds the letters would make individually (like -gh in the word “laugh”). Here are a few more examples: ch (chess), sh (shirt), th (this, bath), gh (ghost, cough), wh (whale, whole), fr (fresh), ck (pick), bl (blue), and sp (spin).

A syllable is basically just one sound in a word. Some words only have one syllable, while others have many syllables. Knowing the number of syllables in a word helps you pronounce it correctly. To use our previous example, the word “day” has three letters, but when you say the word, it only has one unbroken sound.
Every syllable must have at least one vowel, and you can often figure out the number of syllables in a word by looking at the number of vowels. Here are a few examples:
Fast – 1 syllable, 1 vowel (Fast)
Order – 2 syllables, 2 vowels (Or-der)
Tomorrow – 3 syllables, 3 vowels (To-mor-row)
Alligator – 4 syllables, 4 vowels (All-i-ga-tor)
