Dimenticato vs. scordato
In Italian, dimenticato and scordato are synonyms that both translate to "forgotten." While they are often interchangeable, the choice between them usually depends on the level of formality and the regional context. Their etymological roots imply a distinction between losing something from the mind versus losing it from the heart.
Dimenticato
A2This word comes from the Latin word for "mind" (mente). It is the standard, neutral term used to express that something has slipped your memory. It is appropriate for all contexts, including formal writing and professional situations. Generally, dimenticato is universally used throughout Italy without any regional connotation.

(I forgot the keys in the office.)

(The professor forgot to assign the homework.)

(I have never forgotten your help.)

(Did you forget to lock the door?)
Il mondo ha presto dimenticato quell'evento.
(The world soon forgotten that event.)
Scordato
B1This word comes from the Latin word for "heart" (cor or cordis). It originally meant something that exited your heart or feelings, but today it simply means forgotten. It is more colloquial and informal than dimenticato. While understood everywhere, it is slightly more frequent in spoken language and in Central or Southern Italy. It is very often used in its reflexive form, scordarsi.
Mi sono scordato di chiamare la nonna.
(I forgot to call grandma.)

(Don't forget to get the milk!)

Summary
To choose correctly, remember that dimenticato relates to the mind and is perfect for formal or standard Italian. Scordato relates to the heart, is more casual, and adds a warmer or more colloquial tone to the sentence. However, in daily conversation, you can use either without causing confusion.
