Alliteration
Consonance is a broader literary device identified by the repetition of consonant sounds at any point in a word (for example, coming home, hot foot). Alliteration is a special case of consonance where the repeated consonant sound is in the stressed syllable. Alliteration may also refer to the use of different but similar consonants, such as alliterating z with s, as does the author of Sir Gawain and the Green Knight, or as Anglo-Saxon (Old English) poets would alliterate hard/fricative g with soft g (the latter exemplified in some courses as the letter yogh – ȝ – pronounced like the y in yarrow or the j in Jotunheim).
