Loved is the ordinary past participle of love and works anywhere: "she loved him", "a loved one". Beloved is an adjective meaning dearly loved, and it is formal, affectionate and often ceremonial — "our beloved teacher", "dearly beloved". Beloved sits in front of a noun; loved does the grammatical work.
The core difference
Loved is a verb form doing an ordinary job. Beloved is an adjective carrying a register — warmth, reverence, sometimes a touch of the archaic.
- She loved the house. — past tense verb
- The house was loved. — passive
- Their beloved dog. — adjective, dearly loved
You would not write "their loved dog" and you could not write "she beloved the house". They are not interchangeable in either direction.
Where beloved belongs
It appears in eulogies, dedications, wedding services and affectionate description: dearly beloved, beloved by generations of readers. Used casually it can read as arch or ironic, which writers sometimes exploit: "his beloved spreadsheet".
The pronunciation
Beloved has two pronunciations and they are not interchangeable. As an adjective before a noun it usually has three syllables — be-LUV-ed — which is why hymns and liturgy scan the way they do. Used after a verb it is generally two: she was much beloved can go either way. Loved is always one syllable.
Loved one
A loved one is a fixed phrase meaning a close family member or friend, common in medical and funeral contexts. It resists beloved: "a beloved one" is not idiomatic, even though the meaning would be the same.
