multi-sound

Core Rule

Multi-sound letter combinations refer to one spelling producing multiple pronunciations. A classic case is ough / ought, whose sounds vary due to historical sound change and lexical patterns rather than simple phonetic rules.

Articulation Guide

In ought /ɔːt/, the tongue retracts and raises toward the back of the mouth; lips are slightly rounded. Airflow is steady, ending with a light, unreleased /t/. Contrast this with /ʌf/ in rough or /oʊ/ in though.

Word Analysis

• ought /ɔːt/: obligation or logical inference.
• thought /θɔːt/: shares the same rime.
• rough /rʌf/: short vowel plus fricative.
• through /θruː/: long vowel shift.

Pitfalls

Avoid assuming one fixed sound for ough. Instead, group words by rhyme families and verify pronunciation through context and exposure.
