What is a grapheme with 4 letters

A grapheme with 4 letters represents one sound in a word. It is referred to as a ‘tetragraph‘ and ‘quadgraph’ by many teachers.

The letters ‘augh’ in ‘caught’ is considered a ‘quadgraph’ as it sounds like the word ‘or’.

But ‘augh’ in ‘laugh’ is not a ‘tetragraph’. It can be described as a combination of 2 digraphs ‘au’ sounding like ‘ah’ and ‘gh’ sounding like ‘f’ as in ‘laf’.

Similarly, ‘ough’ in ‘though’ is considered a ‘quadgraph’ as it sounds like ‘o’ in ‘cold’.

But ‘ough’ in ‘tough’ and ‘drought’ is not a ‘tetragraph’.

In ‘tough’, it can be described as a combination of 2 digraphs ‘ou’ sounding like ‘uh’ and ‘gh’ sounding like ‘f’ as in ‘tuf’.

In ‘drought’, the ‘ou’ is a diphthong sounding like ‘ow’ and the ‘ght’ is a trigraph sounding like ‘t’.
