PRONUNCIATION OF THE CONSONANTS.
The following letters are pronounced generally as in English: b, d, f, k, l, m, n, p, r, s, t, v, x and y (consonant). It should, however, be noted that the b is slightly softer than in English, as is also the d at or towards the end of a word; that the r is always trilled, the s always hissed, and the t pronounced close to the teeth.
c before a, o, u, and before a consonant, is pronounced like k: capa, cape; crema, cream: before e and i it has the sound of th in bath: cera, wax; cima, summit.
ch is always sounded like ch in check: coche, carriage; ocho, eight.
g before a, o, u, and before a consonant, is pronounced like g in go: goma, gum; grano, grain: before e and i it is sounded like h strongly aspirated in the throat: gente, people; gitano, gipsy. The pronunciation of gua is gwah: guante, glove; guardia, guard; and gue and gui are sounded as in guess and guild, respectively: guerra, war; guitarra, guitar; but güe and güi are pronounced gweh and gwee: vergüenza, shame; lingüista, linguist.
h is always silent: harina, flour; anhelo, eagerness.
j has always the same sound as that given to g before e and i: jabón, soap; hoja, leaf.
ll has a sound very similar to that of lli in million: llave, key; tallo, stalk.
