Alphabet and Sounds
Introduction
Alphabet and Sounds form the foundation of the English language. For competitive examinations such as UPSC, SSC, RRB, Banking (IBPS, SBI), CAT, CDS, NDA, State PSCs, and other government or entrance exams, a strong understanding of alphabets, sounds, pronunciation rules, phonetics, and stress patterns is essential. Many questions in English Language, Verbal Ability, Reading Comprehension, Cloze Test, Error Detection, and Vocabulary are directly or indirectly based on sound knowledge of alphabets and sounds.
This chapter provides complete, exam-oriented, easy-to-understand, and well-structured notes on Alphabet and Sounds, suitable for beginners as well as advanced learners.
1. The English Alphabet
1.1 What is an Alphabet?
An alphabet is a standardized set of letters used to represent the basic sounds of a language in written form. The English alphabet is derived from the Latin alphabet and consists of 26 letters.
1.2 The 26 Letters of the English Alphabet
The English alphabet has 26 letters, divided into:
- Vowels – 5 letters
- Consonants – 21 letters
| Capital Letters (Upper Case) | Small Letters (Lower Case) |
|---|---|
| A B C D E F G H I J K L M | 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 | n o p q r s t u v w x y z |
1.3 Importance of Alphabet in Competitive Exams
Understanding alphabets helps in:
- Alphabet series questions (SSC, RRB)
- Coding–Decoding problems
- Spelling-based error detection
- Pronunciation and phonetic questions
- Vocabulary development
2. Letters vs Sounds
2.1 Difference Between Letters and Sounds
This is one of the most important concepts for learners.
- Letters are written symbols (A–Z)
- Sounds are spoken units (phonemes)
👉 English has 26 letters but about 44 sounds (phonemes).
Example:
- The word cat has 3 letters (c-a-t)
- But it has 3 sounds /k/ /æ/ /t/
Example of mismatch:
- Ship → 4 letters, 3 sounds (/ʃ/ /ɪ/ /p/)
This mismatch is the main reason English spelling and pronunciation seem difficult.
3. Vowels
3.1 What are Vowels?
Vowels are speech sounds produced without blocking the airflow from the mouth. In English, vowels are essential because every word contains at least one vowel sound.
3.2 Vowel Letters
The five vowel letters are:
- A
- E
- I
- O
- U
Sometimes Y also acts as a vowel.
Examples:
- Happy → Y acts as a vowel
- Gym → Y sounds like /ɪ/
3.3 Vowel Sounds
Although there are only 5 vowel letters, English has around 20 vowel sounds.
Vowel sounds are divided into:
- Short Vowels
- Long Vowels
- Diphthongs
- Triphthongs (less common in exams)
4. Short Vowel Sounds
Short vowels are quick and relaxed sounds.
| Sound | Example Words |
|---|---|
| /ɪ/ | sit, pin, ship |
| /e/ | pen, bed, head |
| /æ/ | cat, map, bag |
| /ʌ/ | cup, luck, bus |
| /ɒ/ | hot, pot, cot |
Exam Tip:
Short vowel confusion is common in spelling error and pronunciation-based questions.
5. Long Vowel Sounds
Long vowels sound like the name of the letter itself.
| Sound | Example Words |
|---|---|
| /iː/ | see, tree, seat |
| /ɑː/ | car, father, calm |
| /ɔː/ | law, talk, caught |
| /uː/ | blue, food, school |
| /ɜː/ | bird, work, learn |
Important Note:
Long vowels often appear with:
- Silent ‘e’ (make, cake)
- Double vowels (see, food)
6. Diphthongs
6.1 What is a Diphthong?
A diphthong is a vowel sound that glides from one sound to another within the same syllable.
6.2 Common Diphthongs
| Sound | Example Words |
|---|---|
| /aɪ/ | time, my, eye |
| /aʊ/ | now, out, house |
| /eɪ/ | say, play, rain |
| /oʊ/ | go, home, road |
| /ɔɪ/ | boy, toy, noise |
Exam Relevance:
Diphthongs are frequently tested in phonetic symbol matching questions.
7. Consonants
7.1 What are Consonants?
Consonants are speech sounds produced by partially or completely blocking airflow.
There are 21 consonant letters, but 24 consonant sounds.
7.2 Types of Consonant Sounds
Consonant sounds are classified based on:
- Place of articulation
- Manner of articulation
- Voicing
8. Voiced and Voiceless Sounds
8.1 Voiced Sounds
When vocal cords vibrate.
Examples:
- /b/, /d/, /g/, /z/, /v/
8.2 Voiceless Sounds
When vocal cords do not vibrate.
Examples:
- /p/, /t/, /k/, /s/, /f/
Trick for Exams:
Touch your throat while speaking the sound.
