A stop consonant is a sound that involves a complete closure in the vocal tract so that sound cannot escape the oral cavity. The oral stops of English are [p, t, k, b, d, g], the nasal stops of English are [m, n, ŋ]. In Gaelic, the oral stops are [pʰ, tʰ, kʰ, p, t, k] (written as p, t, c, b, d, g respectively) and the nasal stops are [m, n, N, ŋ] (written as m, n, nn, and ng respectively), including the slender variants thereof.
