📚 What is a Letter?
A letter is the basic building block of written language. Think of it as a single symbol that represents a sound. Letters can be vowels (a, e, i, o, u) or consonants (b, c, d, f, g, etc.). Alone, a letter usually doesn't mean anything, but it's essential for creating words!
✍️ What is a Word?
A word is a group of letters that, when put together, have a specific meaning. Words are used to name things, describe actions, or express ideas. For example, 'cat', 'run', and 'happy' are all words. Words form the basis of communication.
💬 What is a Sentence?
A sentence is a group of words that expresses a complete thought. It usually contains a subject (who or what the sentence is about) and a verb (what the subject is doing). Sentences always start with a capital letter and end with a punctuation mark (like a period, question mark, or exclamation point). For example, 'The cat runs quickly.' is a sentence.
