-ed Adjectives Pronunciation

· Most words ending in -ed follow the same rules as the past-tense inflectional ending.

· Some words ending in -ed have the 'usual' past-tense pronunciation when they are verbs, but end in an /ɪd/ sound as adjectives: blessed, beloved, learned*. 

eg.: The priest blessed /blest/ the bread and wine vs a moment of blessed /ˈblesɪd/ calm

Eric was a teacher beloved /-vd/ by his students vs Her beloved /vɪd/ husband

* the pronunciation of learned may vary according to context when it is an adjective: 

learned /nd/ behaviour (developed by training or experience, not existing at birth).

a learned /ɪd/ man (having a lot of knowledge because of study); 

· Some -ed words always end in an /ɪd/ sound because they are adjectives with no corresponding verbs: naked, aged, cursed, crooked, wretched, rugged, ragged, sacred, wicked, dogged, legged (adjectival in eg three-legged)
