trouthe

• trawthe, treowthe, treuthe, treuþe, trewthe, trowthe, trowþe, truthe

Inherited from Old English trēowþ, trīewþ, from Proto-West Germanic *triuwiþu, from Proto-Germanic *triwwiþō; euivalent to trewe +‎ -the (abstract nominal suffix).

The final vowel is generalised from Old English oblique cases, while forms in /iu̯/ reflect the influence of trewe; the usual vocalism in /ɛu̯/, /ɔu̯/ is due to shortening before the consonant cluster /wθ/ in late Old English.

• IPA^(key): /ˈtrɔu̯ð(ə)/, /ˈtrɛu̯ð(ə)/, /ˈtriu̯ð(ə)/, /-θ(ə)/
• (Early ME) IPA^(key): /ˈtrøwðə/
