Definition

What is it?

A trigraph is a group of three letters that make just one sound. Even though you see three letters, your mouth only makes one sound when you say the word. It's like three friends working together to sing one note.

Simple Example

Quick Example

Imagine you are buying a samosa for ₹20, a chai for ₹10, and a biscuit for ₹5. The total cost is ₹35. You use three different items, but you only pay one total amount. Similarly, in a trigraph, three letters make one sound.

Worked Example

Step-by-Step

Let's find the trigraph in the word 'catch'.

1. Look at the word: c-a-t-c-h.
---2. Try saying each letter sound: /k/ /a/ /t/ /ch/.
---3. Notice the letters 'tch' at the end.
---4. When you say 'catch', the 'tch' makes just one sound, like the 'ch' in 'chai'.
---5. So, 'tch' is the trigraph in 'catch'. It's three letters making one sound.

Answer: The trigraph in 'catch' is 'tch'.

Why It Matters

Understanding trigraphs helps you read and spell better, which is super important for telling stories or writing news. Journalists and authors use clear language, and knowing how letters combine helps them write effectively. This skill is key for anyone who wants to communicate clearly, from writing school essays to creating content for social media.

Common Mistakes

MISTAKE: Thinking a trigraph means three separate letter sounds | CORRECTION: Remember, a trigraph is three letters making ONLY ONE sound, not three different sounds.

MISTAKE: Confusing a trigraph with a blend (where each letter's sound is still heard, like 'bl' in 'blue') | CORRECTION: In a trigraph, the three letters completely merge to form a new, single sound, unlike a blend.

MISTAKE: Not recognizing common trigraphs like 'tch' or 'dge' | CORRECTION: Practice identifying these common groups of letters that often appear together and make one sound.
