consonant digraph

Rule Core

Consonant clusters are groups of two or more consonants pronounced together without inserting a vowel. Each consonant keeps its own sound, forming a smooth yet precise sequence.

Articulation Guide

Maintain continuous airflow. Move the tongue quickly between contact points while keeping the mouth relaxed. Do not slow down or add a schwa between sounds.

Word Analysis (ultra)

In ultra /ˈʌl.trə/, ltr is a consonant cluster across syllable boundary. /l/ touches the alveolar ridge, /t/ releases briefly, and /r/ follows immediately.

Pitfall Alert

Learners often separate clusters or add extra vowels, especially in pl, tr, str combinations.
