The two verses (half-lines) of an Old English poetic line are connected by
alliteration. The first stressed syllable of each verse within a line must alliterate with the first stressed syllable of the other. A second stressed syllable may alliterate in the first verse of a line (this is called
double alliteration), but such extra alliteration is very strictly prohibited in the second verse (which must have
single alliteration). Consonants alliterate with consonants (later consonants in a cluster are ignored, except that
sc,
st, and
sp may each only alliterate with themselves), but a vowel alliterates with any other vowel. As in all
Old English poetry, the alliterative form can be seen in the "
Finnsburg Fragment" (alliterated sounds are in bold): Alliteration only involves elements that carry stress, as discussed in the following section. Old English treats certain sounds as alliterating, even though they are not identical. Specifically: • Unpalatized
c (pronounced ) alliterated with palatized
ċ (pronounced in late Old English), apparently because the sounds were once just one sound (). • Unpalatized
g (pronounced ) likewise alliterated with palatized
ġ (pronounced like
y in
yet, , in late Old English) but also with the
ġ inherited from
Common Germanic . There is not yet a consensus on why these alliterated, but the reason must be partly because the first two
gs were once just one sound. == Stress ==
