How Do You Spell DIDST SOMETHING IT?
Pronunciation: [dˈɪdst sˈʌmθɪŋ ɪt] (IPA) 
The expression "didst something it" is not a common phrase in English. However, it is possible to break down the spelling of each word using IPA phonetic transcription. "Didst" is spelled /dɪdst/ and is the archaic form of "did" in the second person singular (you did). "Something" is spelled /ˈsʌmθɪŋ/ and means a thing of some kind. "It" is spelled /ɪt/ and is a pronoun used to refer to a thing previously mentioned or understood. Therefore, "didst something it" could mean "you did something with it."
