2.1.2. Consonants
Most Old English consonants are pronounced as in Modern English, and most of the differences from Modern English are straightforward:
Old English scribes wrote the letters þ (“thorn”) and ð (“eth”) interchangeably to represent [θ] and [ð], the sounds spelled th in Modern English. Examples: þing ‘thing’, brōðor ‘brother’.
There are no silent consonants. Old English cniht (which comes to Modern English as knight) actually begins with [k]. Similarly hlāf (Modern English loaf) and hring (ring) begin with [h], gnæt (gnat) with [ɡ], and wrīðan (writhe) with [w]. Some Old English consonant combinations may be difficult to pronounce because they are not in Modern English. If you find this to be so, just do your best.
The consonants spelled f, s and þ/ð are pronounced as voiced [v], [z] and [ð] (as in then) when they fall between vowels or other voiced sounds. For example, the f of heofon ‘heaven’, hæfde ‘had’ and wulfas ‘wolves’ is voiced. So are the s of ċēosan ‘choose’ and the ð of feðer ‘feather’. This distinction remains not only in such Modern English singular/plural pairs as wolf/wolves, but also in such pairs as noun bath and verb bathe, noun cloth and derivative clothes.
These same consonants were pronounced as unvoiced [f], [s], and [θ] (as in thin) when they came at the beginning or end of a word or adjacent to at least one unvoiced sound. So f is unvoiced in ful ‘full’, cræft ‘craft’ and wulf ‘wolf’. Similarly s is unvoiced in settan ‘set’, frost ‘frost’, and wulfas ‘wolves’, and þ/ð is unvoiced in þæt ‘that’ and strengð ‘strength’.
When written double, consonants must be pronounced double, or held longer. We pronounce consonants long in Modern English phrases like “big gun” and “hat trick,” though never within words. In Old English, wile ‘he will’ must be distinguished from wille ‘I will’, and freme ‘do’ (imperative) from fremme ‘I do’.
This book sometimes prints c with a dot (ċ) and sometimes without. Undotted c is pronounced [k]; dotted ċ is pronounced [ʧ], like the ch in Modern English chin. This letter is never pronounced [s] in Old English. It has a special function in the combination sc (see item 10 below).
The letter g, like c, is sometimes printed with a dot and sometimes without. Dotless g is pronounced [ɡ], as in good, when it comes at the beginning of a word or syllable. Between voiced sounds dotless g is pronounced [ɣ], a voiced velar spirant.[3] This sound became [w] in Middle English, so English no longer has it. Dotted ġ is usually pronounced [j], as in Modern English yes, but when it follows an n it is pronounced [ʤ], as in Modern English angel.
The combination cg is pronounced [ʤ], like the dge of Modern English sedge. Examples: hrycg ‘ridge, back’, brycg ‘bridge’, ecg ‘edge’.
Old English h is pronounced [h], as in Modern English, at the beginnings of syllables, but elsewhere it is pronounced approximately like German ch in Nacht or ich—that is, as a velar [x] or palatal [ç] unvoiced spirant (pronounced with the tongue against the velum [soft palate] or, after front vowels, against the hard palate). Examples: nēah ‘near’, niht ‘night’, þēah ‘though’, dweorh ‘dwarf’.
The combination sc is usually pronounced [ʃ], like Modern English sh: scip ‘ship’, æsc ‘ash (wood)’, wȳscan ‘wish’. But within a word, if sc occurs before a back vowel (a, o, u), or if it occurs after a back vowel at the end of a word, it is pronounced [sk]: ascian ‘ask’ (where sc was formerly followed by a back vowel), tūsc ‘tusk’. When sc was pronounced [sk] it sometimes underwent metathesis (the sounds got reversed to [ks]) and was written x: axian for ascian, tux for tusc. Sometimes sc is pronounced [ʃ] in one form of a word and [sk] or [ks] in another: fisc ‘fish’, fiscas/fixas ‘fishes’.
