Letters in English Grammar: A Simple Guide for Teens

Letters are the basic building blocks of English. They form words, which form sentences, and help us read, write, and speak.


What is a Letter?

A letter is a symbol used in writing.

  • Letters join together to make words.
  • Each letter represents a sound.

Example:

  • Letters: c, a, t → Word: cat → a small animal

Think of letters as building blocks of English.


The English Alphabet

The English alphabet has 26 letters:

  • Uppercase (Capital letters): A, B, C … Z
  • Lowercase (Small letters): a, b, c … z

Tip: Uppercase letters are used at the start of sentences and for names, titles, and acronyms.


Vowels and Consonants

Letters are divided into vowels and consonants.

  • Vowels: a, e, i, o, u (sometimes y) – they make open sounds.
    Examples: apple, elephant, ice
  • Consonants: All other letters – they block or restrict air.
    Examples: bat, dog, fish
  • Semi-vowels: y, w – can be vowel or consonant.
    Examples: yes (consonant), fly (vowel)

Uppercase vs Lowercase Letters

  • Uppercase: Start of sentences, names, titles → Emma, London
  • Lowercase: All other words → I like chocolate

Tip: Always capitalize the pronoun “I”.


Letter Sounds

  • Each letter has a name and one or more sounds.
  • Some letters sound different in different words.

Examples:

  • c → cat /k/, city /s/
  • g → go /g/, giant /j/
  • a → cat /æ/, cake /eɪ/

Alphabetical Order

  • Letters go from A → Z.
  • Used in dictionaries, lists, and files.

Example: apple, ball, cat, dog


Forming Words

  • Letters join in order to make words.
  • Every word needs at least one vowel.

Examples:

  • h + a + t → hat
  • s + u + n → sun

Tip: Practice making words from scrambled letters to improve spelling.
