SOURCE: Germanic */g/
OE /g/ had three different realizations, or allophones, depending upon its phonetic environment.
1. Voiced velar stop--before consonants, back vowels, or front vowels resulting from umlaut . Example: god "good."
REFLEX: ME /g/
2. Voiced velar fricative--between back vowels or after OE /l/ or OE /r/. Examples: burg "borough"; sagu "saying."
REFLEX: ME /w/ [See "Vocalizing of velar fricative." ]
3. alveopalatal semivowel--in vicinity of front vowels. Examples: gear "year." This allophone of OE /g/ merged with the phoneme OE /j/ inherited from Germanic.
REFLEX: OE /j/
SPELLING: g, 3
