hard c

Rule Core

The hard c rule states that the letter c is pronounced /k/ when it appears before a, o, or u. This follows a strong-vowel logic in English phonics and remains highly consistent in academic and multisyllabic vocabulary.

Articulation Guide

Raise the back of the tongue to contact the soft palate, creating a full stop. Release the air sharply without vocal cord vibration. The mouth stays slightly open with no added aspiration.

Word Analysis

accommodation: the initial c precedes a, producing /k/; the doubled cc does not soften the sound. accountancy: cc before o clearly signals /k/. accusation: the first c before a is /k/; the sequence cu is pronounced /kju/, still anchored in the hard c system.

Pitfall Guide

Do not assume long words or double letters weaken the sound. As long as c is followed by a, o, or u, it remains hard. Strictly separate this from soft c patterns before e, i, and y.
