Pronunciation: [dˈɪdst wˈɒʃɪŋ] (IPA) 
"Didst washing" is an archaic phrase that means "you washed" in the past tense. The spelling of "didst" is pronounced as /dɪdɪst/, with the "st" added as a contraction of "did" and "est". The word "washing" is pronounced as /wɒʃɪŋ/, with the "sh" sound representing the "sh" phoneme. This spelling is typical of Middle English and Early Modern English language, and is not commonly used in modern English.
The phrase "didst washing" is not a standard English phrase. However, if we break it down into two parts, we can explore their individual etymologies:
1. "Didst": "Didst" is the second-person singular past tense of the auxiliary verb "do" in Early Modern English. It was predominantly used in Early Modern English (roughly from the 15th to the 17th century) and is no longer part of standard modern English. The etymology of "didst" traces back to the Middle English word "didest" and ultimately to the Old English "dyde" or "didon", meaning "did".
2. "Washing": The word "washing" comes from the noun form of the verb "to wash".
